You asked: What is the volume of a mole of gas?

How do you find the molar volume of a gas?

At standard Temperature and Pressure (STP) the molar volume (Vm) is the volume occupied by one mole of a chemical element or a chemical compound. It can be calculated by dividing the molar mass (M) by mass density (ρ). Molar gas volume is one mole of any gas at a specific temperature and pressure has a fixed volume.

What is a mole of gas?

The Mole. A mole (abbreviated mol) of a pure substance is a mass of the material in grams that is numerically equal to the molecular mass in atomic mass units (amu). … One mole of an ideal gas will occupy a volume of 22.4 liters at STP (Standard Temperature and Pressure, 0°C and one atmosphere pressure).

What is the mole formula?

Avogadro’s number is a very important relationship to remember: 1 mole = 6.022×1023 6.022 × 10 23 atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro’s number. To convert from atoms to moles, divide the atom amount by Avogadro’s number (or multiply by its reciprocal).

How do you find moles from molar volume?


There are two steps: Multiply the volume by the density to get the mass. Divide the mass by the molar mass to get the number of moles.

How do you calculate moles from volume?

Converting from moles to volume (liters): Multiply your mole value by the molar volume constant, 22.4L. Converting from particles (atoms, molecules, or formula units) to moles: Divide your particle value by Avogadro’s number, 6.02×1023. Remember to use parentheses on your calculator!

How many liters are there in 2 moles of nitrogen gas?

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. Since there are two moles of gas present, the volume is doubled.

What is the volume of 1 mole of gas at NTP?

where P is the pressure of the ideal gas, V is the volume of the given sample, n is the number of moles present in the given sample, T is the temperature and R is the gas constant. Thus the volume of one mole of gas at NTP is obtained as V=24⋅04×10−3m3=24⋅04L .
