N76 [4]

The answer to fill in the blank would be B) because say for ex you are sick and your mom checks your temperature, she is doing this to see how hot/cold are you, so she is checking your body to see how you are, so same with this, temperature basically measures the kinetic energy/motion of particles in something.

In experiment 1, how many moles of benzoic acid are present? how many moles of sodium bicarbonate are contained in 1 ml of a 10%

nexus9112 [7]

First, let us calculate the moles of solute or sodium bicarbonate is in the 1 ml solution.

moles = 1 mL * (1 g / 9 mL) = 0.11 moles

The molar mass of sodium bicarbonate is 84 g/mol, therefore the mass is:

mass = 0.11 moles * 84 g/mol

mass = 9.33 g

Answer:

Avogadro's Law; 15.1L

Explanation:

Boyle's Law- Pressure and volume are inversely related, so an increase in pressure= decrease in volume. We see this in the equation P1V1=P2V2.

Charle's Law- Gas expands/increases in volume when temperature increases, so they are proportional. We see this in the formula $\frac{V1}{T1} = \frac{V2}{T2}$ .

Guy-Lussac's Law- As temperature increases, pressure increases, so they are proportional. We see this in the formula $\frac{P1}{T1} = \frac{P2}{T2}$ .

Avogadro's Law- There are equal amount of volume have an equal amount of moles, so they are proportional. We see this in the formula $\frac{V1}{n1} = \frac{V2}{n2}$ .
