# What is the value of gram molecular volume?

## What is the value of gram molecular volume?

At Standard Temperature and Pressure 1 mole or gram molecular weight of a substance occupies 22.4 L of volume.

## What is GMV law in chemistry?

GMV means gram molar volume. According to which every gas has fixed no. of molecules in a particular fixed volume at a given temperature and pressure or under standard conditions i.e the volume taken by 1 mole of a gas at particular standard temperature and pressure condition is called as GMV.

What is gram molar volume GMV?

The volume occupied by one gram molecular mass or one mole of gas under standard conditions (273 K and 760 mm pressure) is called gram molecular volume (GMV). Its value is 22.4 litres for each gas.

### What is the value of molecular volume?

The molar volume of a gas is the volume of one mole of a gas at STP. At STP, one mole (6.02×1023 representative particles) of any gas occupies a volume of 22.4L (figure below). Figure 10.13. 2: A mole of any gas occupies 22.4L at standard temperature and pressure (0oC and 1atm).

### What is the volume of 1 gram molecule of oxygen gas?

Hence, gram molecular volume of oxygen gas at STP is $22400{\text{ c}}{{\text{m}}^3}$ and the correct option is (C). Note: The value of pressure, temperature, moles and R should be taken with a proper unit system.

What is the formula of gram molecular weight?

Using the periodic table of the elements to find atomic weights, we find that hydrogen has an atomic weight of 1, and oxygen’s is 16. In order to calculate the molecular weight of one water molecule, we add the contributions from each atom; that is, 2(1) + 1(16) = 18 grams/mole.

#### How to calculate molecular mass using volume law?

Calculator of Molecular Mass using Gram Molecular Volume Law Formula of Molecular Mass using Gram Molecular Volume Law Molecular mass = 2 x Vapour density Vapour density = Density of gas / Density of hydrogen

#### Which is the correct definition of Gram molecular volume?

gram-molecular volume, amount of a molecular substance whose weight, in grams, is numerically equal to the molecular weight of that substance.

How to calculate the gram molecular weight of a gas?

By Avogadro’s Law 22.4 liters of any other gas at STP will contain the same number of molecules as a mole of oxygen. Thus 22.4 liters of any gas at STP contains exactly one mole of the gas. Consequently if we know the weight of a gas we can compute its gram-molecular weight.

## How to calculate molar volume and Avogadro’s law?

In these lessons, we will learn the Molar Volume, Avogadro’s Law, how to calculate gas volumes given moles and grams, how to calculate moles given gas volumes and how to calculate gas volumes given the chemical equation.
