## What is molar volume of a gas What will be the volume of 3 moles of o2 gas at STP?

3 moles of oxygen at STP will occupy a volume of 3×22. 4=**67**.

## What is the volume of 3 moles of gas?

So, if 1 mole occupies 22.4 L, the imediate conclusion is that a bigger number of moles will occupy more than 22.4 L, and a smaller number of moles will occupy less than 22.4 L. In your case, 3 moles of gas will occupy **3 times more volume than 1 mole of gas**.

## What is the volume in Litres at STP of 3 moles of h2s gas?

Explanation: Well, assuming that the hydrogen gas is contained at STP , then the molar volume would be 22.7⋅3=**68.1 L** .

## What is STP formula?

**V _{STP} = V * (273.15/T) * (P/760)** This STP formula uses Kelvins, Torrs and Liters.

## What’s the volume of hydrogen gas?

The actual molar volume of hydrogen can be exactly calculated from the experimental density of that gas, that is 0,0899 g/L at 0 °C (1 atm ) and **0.0837 g/L at** 20 °C (1 atm), knowing that one mole of dihydrogen ( H2 ) amounts to 2,0159 g/mol.

## What is the volume of gas at NTP?

Volume of gas at NTP is **1.12×10−7cm−3** .

## How do you find the volume of a gas 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.

## What is the volume of n2 at STP?

Using Molar Volume : Example Question #1

What is the volume of two moles of diatomic nitrogen gas at STP? Explanation: One mole of gas has a volume of **22.4L** at STP.
