A mole is related to concentration in a solution as in option 2: The number of particles of solute in a solution is measured in moles.

The Avogadro's number is defined as:

A = 6.022x10²³ mol⁻¹

Hence, in 1 mole we have 6.022x10²³ particles, or atoms, or molecules, or other.

Let's evaluate every option.                  

1. The saturation point of a solution is measure in moles. False

The saturation point indicates how is the solubility of a solute in a solution. Its units are given in the amount of solute (mol, g, or L) per unit of solution (L or g).    

2. The number of particles of solute in a solution is measured in moles. True

As we said above, in 1 mole we have 6.022x10²³ particles of solute in a solution.

           

3. The volume of particles of solute in a solution is measured in moles. False

The volume of a solution is measured in liters (L) or m³, not in moles.

         

4. The mass of the solute in a solution is measured in moles. False

The mass is measured in kilogram (kg), not in moles.

Therefore, the correct option is 2: The number of particles of solute in a solution is measured in moles.

Balance the reaction for the combustion of pentane: ?C5H12+?O2→?CO2+?H2O Enter the four coefficients in order, separated by comm
Daniel [21]

Answer:

The four coefficients in order, separated by commas are 1, 8, 5, 6

Explanation:

We count the atoms in order to balance this combustion reaction. In combustion reactions, the products are always water and carbon dioxide.

C₅H₁₂  +  ?O₂→  ?CO₂ + ?H₂O

We have 12 hydrogen in right side and we can balance with 6 in the left side. But the number of oxygen is odd. We add 2 in the  right side, so we have 24 H, and in the product side we add a 12.

As we add 2 in the C₅H₁₂, we have 10 C, so we must add 10 to the CO₂ in the product side.

Let's count the oxygens: 20 from the CO₂ + 12 from the water = 32.

We add 16 in the reactant side. Balanced equation is:

2C₅H₁₂  + 16O₂→  10CO₂ + 12H₂O

We also can divide by /2 in order to have the lowest stoichiometry

C₅H₁₂  + 8O₂→  5CO₂ + 6H₂O

The density of water at 30.0 °C is 0.9956 g/mL. If the specific gravity of acetic acid is 1.040 at 30.0 °C, what is the density
mash [69]

Answer:

The density of acetic acid at 30°C = 1.0354_g/mL

Explanation:

specific gravity of acetic acid = (Density of acetic acid at 30°C) ÷ (Density of water at 30°C)

Therefore, the density of acetic acid at 30°C = (Density of water at 30°C) × (Specific gravity of acetic acid at 30°C)

= 0.9956 g/mL × 1.040

= 1.0354_g/mL

Specific gravity, which is also known as relative density, is the ratio of the density of a substance to the density of a specified standard substance.

Generally the standard substance of to which other solid and liquid substances are compared is water which has a density of 1.0 kg per litre or 62.4 pounds/cubic foot at 4 °C (39.2 °F) while gases are normally compared with dry air, with a density of 1.29 grams/litre or 1.29 ounces/cubic foot under standard conditions of a temperature of 0 °C and one standard atmospheric pressure

Consider the model of the nitrogen atom which electron configuration matches the model
san4es73 [151]

Answer:

           1s², 2s², 2p³  

Explanation:

The atomic number of Nitrogen is seven. So it contains seven protons and seven electrons in neutral form. Also, the electronic configuration cited above contains seven electrons among which two electrons are present in first shell and five electrons are present in valence shell respectively.
