## How do you convert moles to volume at STP?

Molar volume at STP can be used to convert from moles to gas volume and from gas volume to moles. The equality of **1mol=22.4L** is the basis for the conversion factor.

## How do you find moles of hydrogen gas from volume?

**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 volume will 5.0 g of h2 occupy at STP?

So, you know that under STP conditions for pressure and temperature, 1 mole of any ideal gas will occupy **22.4 L** .

## How do you find volume at STP?

It can be written as: **V = nRT/P**. “P” is pressure, “V” is volume, n is the number of moles of a gas, “R” is the molar gas constant and “T” is temperature. Record the molar gas constant “R”. R = 8.314472 J/mole x K.

## What is the value of hydrogen gas at STP?

Make a prediction regarding your numerical expectation of how your experimentally derived molar volume of hydrogen gas (corrected to STP) will compare with the accepted theoretical value of **22.4L/mole**.

## What is the volume of 3 moles of hydrogen gas at STP?

At STP, 1 mole of hydrogen can occupy a volume of 22.4 liters. At STP, 3 moles of hydrogen can occupy a volume of 2×22. 4=**44.** **8 liters**.
