The given Ideal Gas Molar Mass Calculator effortlessly calculates the moles and molar mass of gas. To discover the result fast, simply enter the mass, volume, temperature, and pressure details in the specified input areas and press the calculate button.

Molar Mass Of Gas

Mole and Molar Mass - Definitions

A mole is a metric unit for measuring stuff. There are exactly 6.02214076 x 10^23 elementary particles in each mole. The weight of one mole in a given substance is described by the unit gramme per mole.

Molar mass, atomic mass, and molecular mass are all various terms for the same thing. The mass of one mole of a substance is referred to as molar mass. Atomic mass refers to the mass of a single atom in a substance, while molecular mass refers to the mass of a single molecule in a substance.

Ideal Gas Law Formula

This ideal gas law formula can be used to calculate the number of moles in a substance. The formula is as follows Moles = (Pressure * Volume) / (0.0821 * Temperature)

The molar mass equation is molar mass = mass/moles

How to Calculate the Molar Mass of a Gas?

These are the easy steps for quickly calculating the molar mass of a gas. Follow these guidelines and rules.

  • Step 1: Know the Volume, mass, pressure, and temperature.
  • Step 2: Multiply the pressure and volume by a factor of ten.
  • Step 3: To find the number of moles, divide the result by the product of 0.0821 and temperature.
  • Step 4: To determine the molar mass of a gas, divide its mass by the number of moles.

How to Use the Molar Mass Of a Gas Calculator?

The following is the procedure for using a gas calculator's molar mass:

  • Step 1: Fill in the appropriate input fields with the volume, mass, temperature, and pressure of a gas.
  • Step 2: To get the output, click the "Calculate Molar Mass" button.
  • Step 3: Finally, in the output field, the value of a gas's molar mass will be displayed.

Molar Mass Of a Gas Examples

Question 1: Calculate the molar mass of a gas with a volume of 30 cm^3, a mass of 7g, a temperature of 20 degrees Celsius, and a pressure of 25 atmospheres.



Volume of the gas = 30 cm^3

Mass = 7 g

Temperature = 20 celcius

pressure = 25 atm

Number of moles = (Pressure * Volume) / (0.0821 * Temperature)

= (25 x 30)/(0.0821 x 20)

= 456.76

molar mass = mass/moles

= 7/456.76

= 15.32 x 10^-3

Hence, the molar mass of gas is 15.32 x 10^-3 g/mol.

FAQ’s on Molar Mass of a Gas

1. What is the formula for calculating molar mass?

To get a molecule's molar mass, we must first determine the atomic weights of the various elements in a periodic table. The number of atoms is then multiplied by the individual atomic masses. Finally, we calculate the molar mass by adding all of the atomic masses together.

2. What exactly is the distinction between a mole and a molar mass?

The molar mass of a substance is defined as the mass of 6.022 x 10^23 atoms, molecules, or formula units in 1 mol of that substance, expressed in grammes per mole.

3. What is the purpose of the molarity calculator?

A free online molarity calculator is a handy tool for calculating the mass of a substance needed to make a solution of known volume and concentration. The volume of solution required to dissolve a known mass chemical to the desired concentration.

4. What is the molar mass of the gas?

The mass of the sample divided by the amount of material is the molar mass of a chemical compound. The mass of a single gas particle multiplied by the Avogadro number gives the molar mass of that gas.
