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.

Answer:

1. 3 covalent bonds

2. CO2

Nitrogen can form three covalent bonds and carbon dioxide  represents a covalent compound.Molecule of nitrogen is attached in image below.

Covalent bond is defined as a type of bond which is formed by the mutual sharing of electrons to form electron pairs between the two atoms.These electron pairs are called as bonding pairs or shared pair of electrons.

Due to the sharing of valence electrons , the atoms are able to achieve a stable electronic configuration . Covalent bonding involves many types of interactions like σ bonding,π bonding ,metal-to-metal bonding ,etc.

Sigma bonds are the strongest covalent bonds while the pi bonds are weaker covalent bonds .Covalent bonds are affected by electronegativities of the atoms present in the molecules.Compounds having covalent bonds have lower melting points as compared to those with ionic bonds.

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

1. Genetic factors are those where the genetic condition of an individual is capable of increasing the probability of developing certain diseases.

Environmental factors include the diversity of environmental stresses such as population density, temperature, food and pollutants that impact human health.

Social factors are related to the interaction of groups through culture, social class and family structure, which also have an effect on population health.

Pathogenic factors, on the other hand, are those transmitted by agents such as viruses, fungi, bacteria and protozoa, which colonize a host by adhering to cells and evading immunity, generating diseases.

2. The transmission of pathogens can occur in several ways, such as contact with bodily fluids from infected people, cross-transmission or through being spread through particles in the air.

3. We can prevent the transmission of pathogens through proper hygiene habits, healthy eating, vaccination against infectious diseases and avoid contact with other people if you have a communicable disease.

4. The environment can affect personal health through climate change, pollution and lack of infrastructure that lead to less access to quality food and basic health conditions.

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.

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.

Hence, to bring about locomotion skeletal and are responsible.

A: Cancer that affects the blood

information: Leukemia is a cancer of the early blood-forming cells. Most often, leukemia is a cancer of the white blood cells, but some leukemias start in other blood cell types.

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.

Answer:

0.32L

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.
= 0.32 L
