A plot of the effect of temperature on the volume of a gas at constant pressure shows that the volume of a gas is directly proportional to the number of moles of that gas. This is stated as Avogadro’s law.

## What is the relationship between mole and volume?

At constant temperature and pressure the volume of a gas is directly proportional to the number of moles of gas.

## How do you calculate volume in moles?

MOLES FROM VOLUME OF PURE LIQUID OR SOLID

Multiply the volume by the density to get the mass. Divide the mass by the molar mass to get the number of moles.

## What is the mole conversion for volume?

Molar volume at STP can be used to convert from moles to volume and from volume to moles for gaseous samples. The fact that 1 mole = 22.4 L is the basis for the conversion factor.

## Do moles increase with volume?

According to Avogadro’s law, as the number of moles of gas increases the volume also increases.

## How do you find moles with volume and molarity?

To calculate the number of moles in a solution given the molarity, we multiply the molarity by total volume of the solution in liters.

## What is the formula for calculating moles?

Divide the number of grams of each reactant by the number of grams per mole for that reactant. 50.0 g of Na are used in this reaction, and there are 22.990 g/mol. 50.0 ÷ 22.990 = 2.1749. 2.1749 moles of Na are used in this reaction.

## What is the volume formula?

Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.
