A student wants to test for the concentration of food dye FD&C Yellow #5 (Tartrazine) in a yellow Starburst candy. First, the student must prepare standard solutions for the calibration curve. The student has a stock solution of FD&C Yellow #5; the concentration is 0.1140 M. The student takes 6.50mL of the stock solution and dispenses it into a 50.0mL volumetric flask. The flask is then diluted to volume with water. What is the concentration of this standard solution?

Answers

The molarity of the diluted standard solution is obtained by calculation to be 0.015 M.

Recall the dilution formula;

C1V1 = C2V2

C1 = Initial concentration = 0.1140 M

V1 = initial volume =  6.50mL

C2 = Final concentration = ?

V2 = Final volume = 50.0mL

Making C2 the subject of the formula and substituting values;

C2 = C1V1/V2

C2 = 0.1140 M ×  6.50mL/50.0mL

C2 = 0.015 M

Answer: A. 8.8%

Explanation:

Percent Error Formula: approximate error - actual value divided by actual value (Approximate-Actual/Actual). After those steps are completed, multiply by 100 to make it a percentage form.

0.365 - 0.400 = -0.035

-0.035 / 0.400 = 0.0875

0.0875 * 100 = 8.75%

What is the molarity of a solution of 3.0 mol of KCl in 4.0L of water?

Answers

The number of moles of a solute per liter of solution is measured using the unit of concentration known as molarity.

Thus, The approach for resolving molarity issues is quite straightforward. This describes an easy way to figure out how molarity of a solution.

Remembering the units of molarity (M): moles per liter, is the key to calculating molarity. Calculate how many moles of the solute are dissolved in a solution's liter volume to determine its molarity.

The molarity of a solution made by combining 23.7 grams of KMnO4 with 750 mL's worth of water. You must first determine the amount of moles of the solute because this example lacks the liters or moles required to determine molarity.

Thus, The number of moles of a solute per liter of solution is measured using the unit of concentration known as molarity.

Zn + Fe2O3 --> Fe + ZnO
If excess Zn reacts with 1.34g Fe2O3 in the reaction above, how many grams of Fe would you expect to be produced

Answers

The mass of Fe produced from the reaction is 0.938 g.

We'll begin by calculating the mass of Fe2O3 that reacted and the mass of Fe produced from the balanced equation.

3Zn + Fe₂O₃ —> 2Fe + 3ZnO

Molar mass of Fe₂O₃ = (56×2) + (16×3) = 160 g/mol

Mass of Fe₂O₃ from the balanced equation = 1 × 160 = 160 g

Molar mass of Fe = 56 g/mol

Mass of Fe from the balanced equation = 2 × 56 = 112 g

From the balanced equation above,

160 g of Fe₂O₃ reacted to produce 112 g of Fe.

Finally, we shall determine the mass of the Fe produced by 1.34 g of Fe₂O₃

From the balanced equation above,

160 g of Fe₂O₃ reacted to produce 112 g of Fe

Therefore,

1.34 g of Fe₂O₃ will react to produce = (1.34 × 112)/160 = 0.938 g of Fe

Thus, 0.938 g of Fe was produced from the reaction.

Answers

Answer:

12.5%

Explanation:

percent blurf = quantity of blurftotal quantity×100quantity of blurftotal quantity×100

So for percent by mass, both quantities are expressed as mass, and it’s the mass of NaCl divided by the total mass of the solution, then times 100%

mass % NaCl = 25 g/175g×100

mass %NaCl = 14.3%

which two body systems are primarily responsible for locomotion

Answers

Locomotion and movement are brought about by skeletal and muscular system of the body. It’s a coordinated event of the skeletal and muscular system brought by contraction and relaxation of muscles.

How does locomotion occur in our body?

Locomotion occurs with help of specialised muscles, muscular and non-muscular by nature.

It involves the interaction of muscles (tendons and ligaments) and skeletal joints and cartilage

Locomotion is a voluntary action which require involvement of the nervous system.

In muscles actin and myosin protein forms cross bridges, consuming ATP.

Explanation:

Use formula of V= wt/mm•M.
To get this information we need to first get the molar mass (mm).
mm:
K - 2 x 39.09
S - 1 x 32.06
K2S - 110.262 g/mol

Now we plug it back into the equation.
3.5g/ (110.262 g/mol) • (0.100M)
= 0.317 L of solution

To round to the correct number of siginficant figures the answer is.

Many things that we use every day, like televisions, computers, refrigerators, and microwaves, require energy in order to work. We also rely on energy to make a car run and to heat water. All of the energy that we need to use must first be produced. Some sources of energy, such as gas and oil, can be harmful to the environment. Burning gas and oil can pollute the air. Also, gas and oil are limited, and we are using up the small amount that is left on the planet. This is why people should use alternative energy sources, which do not pollute the environment and are plentiful. Solar and wind energy are clean energy sources that should be used more often to reduce the pollution on Earth.Which text structure does the author use to organize the passage?
