What is density?
A material's density specifies the density of that material in a given region. The mass per unit volume of a material is defined as its density. The density of matter is a measurement of how tightly stuff is packed together. It is a specific physical property of anything. The density principle was established by Archimedes, a Greek scientist. Calculating density is simple if you know the formula and understand the units. The symbol denotes density, which can also be represented by the letter D.
Understanding density is critical since it affects many aspects of life. In physics, density is something that affects which clouds float high in the sky and which sink lower. The motions of gases in the atmosphere are determined by density when one material rises over another. It has an impact on what sinks and what floats in a body of water. So, what exactly does density imply? The definition of density is a measure of how dense matter is. Simply put, how much "things" can fit into a given space. The more "stuff" or substance crammed into a place, the denser it becomes.
Calculate the mass of NH3 in household ammonia as follow
[NH3] = weight of NH3 ( Density of water)
[NH3]= 30Kg/[tex]m^{3}[/tex]
[NH3] IN mg/L
Therefore the concentration of NH3 is 30000mg/L.

When three molecules of carbon dioxide (co2) react with three molecules of rubp during the calvin cycle, six molecules of the sugar g3p are produced. One g3p molecule exits the calvin cycle during phase 2. What happens to the other five g3p molecules?.
Three molecules of ribulose-1,5-biphosphate are generated from the remaining five G3P molecules.
What is Calvin cycle?Calvin cycle, also known as the photosynthesis's light-independent phase. In this stage, glucose is synthesized using the NADPH and ATP created during the light stage.
There are three primary phases of the Calvin cycle: carbon fixation, reduction, and regeneration.
In the process of fixing carbon, ribulose-1,5-biphosphate, a CO2 acceptor, combines with three molecules of CO2 to produce two molecules of 3-phosphoglycerate. This reaction is catalyzed by RUBISCO (PGA)
PGA is reduced by NADPH during the reduction stage, and ATP phosphorylates PGA to generate six molecules of glyceraldehyde-3-phosphate (G3P). According to the answer, while the other five molecules of G3P continue in the cycle, one leaves it to be used to create glucose.
The initial five molecules of G3P are rearranged into three molecules of the five-carbon CO2 acceptor known as ribulose-1,5-biphosphate during the third stage, dubbed the regeneration stage (RUBP).

Which of the noble gases should show the greatest deviation from the ideal gas law at high pressures?.
Xenon a noble gas shows the greatest deviation from the ideal gas law at high pressures.
Real gases behave very differently from ideal gases at high pressures or low temperatures. It's useful to be aware that the ideal gas law considers the size of gas molecules to be minimal or nonexistent.
Due to its size and the fact that it is the largest of the group, Xe is predicted to deviate from the ideal gas the most under conditions of high pressure or low temperature.
Van der Waal forces come into play as gaseous atoms or molecules grow closer to one another under high pressure and low temperature. As a result, atoms or molecules begin to attract one another. As a result, gas behaves the furthest from its ideal state. While in an ideal world there would be no intermolecular forces of attraction, we can assume that gases do not attract one another.

The relationship between absorbance of light by a solution and its concentration should be Linear
b) Linear
so that when concentration increases, absorbance Increases
c) Increases
The Beer-Lambert Law, also known as the Beer-Lambert-Bouguer Law, describes the relationship between the absorbance of light by a solution and the concentration of the absorbing solute in that solution. This law is fundamental in spectroscopy and is used to quantify the concentration of a solute in a solution.
The Beer-Lambert Law is expressed as:
A = ε * c * l
Where:
A is the absorbance of the solution (unitless),
ε is the molar absorptivity or molar extinction coefficient (a constant specific to the solute and the wavelength of light),
c is the concentration of the solute in the solution (usually in mol/L or M),
l is the path length of the light through the solution (usually in centimeters).
The relationship between absorbance of light by a solution and its concentration should be: Linear
so that when concentration increases, absorbance: Increases
In a linear relationship, the absorbance of light by a solution increases in direct proportion to the concentration of the solute in the solution. As the concentration of the solute increases, more light is absorbed by the solution, leading to a higher absorbance value.
Therefore, when the concentration of a solution increases, the absorbance of light by that solution also increases in a linear fashion.

The percent yield will be 103 %
Mass of potassium bicarbonate = 1.00 g
Molar mass of potassium bicarbonate = 100.115 g/mol
Mass of potassium carbonate = 0.710 g
Molar mass of potassium bicarbonate = 138.205 g/mol
Calculated yield = 0.690 g
Percent yield = ?
Calculated yield is given, if not you can find out by following steps:
Write the balanced chemical equation
2KHCO₃ → K₂CO₃ + H₂O + CO₂
Hence 2 moles of KHCO₃ decompose to produce 1 mole of K₂CO₃
This means that 2 × 100.115 g of KHCO₃ will produce 138.205 g of K₂CO₃
Calculate for 1 g = 138.205 / 200.23
Calculate for 1 g = 0.690 g
This means that 1 g of KHCO₃ will produce 0.690 g of K₂CO₃
Now calculate % yield
% yield = (actual yield / calculated yield)
