## How do you find the number of moles of a gas at STP?

To go from grams to moles, **divide the grams by the molar mass**. 600 g58.443 g/mol = 10.27 mol of NaCl. It has been found that 1 mol of any gas at STP (Standard Temperature and Pressure = 0 °C and 1 atm) occupies 22.4 L. 6.00 mol×22.4 L1 mol = 134.4 L of CO.

## What is the number of moles in STP?

At Standard Temperature and Pressure (STP), 1 mole of any gas will occupy a volume of **22.4 L**. The Ideal Gas Law, along with a balanced chemical equation, can be used to solve for the amount, either in volume or mass, of gas consumed or produced in a chemical reaction.

## How do you find moles of gas?

**Multiply the volume and pressure and divide the product by the temperature and the molar gas constant** to calculate moles of the hydrogen gas. In the example, the amount of hydrogen is 202,650 x 0.025 / 293.15 x 8.314472 = 2.078 moles.

## What is the variable for 22.4 L?

**Standard temperature and pressure** (STP) are a useful set of benchmark conditions to compare other properties of gases. At STP, gases have a volume of 22.4 L per mole.
