# What is the mass of 0 2 mole?

Contents

One mole of oxygen gas, which has the formula O2, has a mass of 32 g and contains 6.02 X 1023 molecules of oxygen but 12.04 X 1023 (2 X 6.02 X 1023) atoms, because each molecule of oxygen contains two oxygen atoms.

## What is the mass of 0.2 mole?

-Therefore, the mass of 0.2 moles of oxygen atom is 3.2 grams and the mass of 0.5 moles of a water molecule is 9.0 grams.

## What is 0.5 mole mass?

Mass of 0.5 mole of water is 9g.

## What is the mass of 0.2 mole of water?

Moles of H2O = 0.2. Mass / ( 1* 2 + 16 ) = 0.2. Mass = 0.2 × 18. Mass of H2O = 3.6 gm.

## What is mass of 0.2 moles of oxygen?

Therefore mass of 0.2 moles of Oxygen molecule is equal to 6.4 grams.

## What is the mass of 0.2 mole of oxygen atoms Brainly?

The molecular weight of Oxygen is twice the atomic weight (since Oxygen is diatomic)=16*2=32 . Thus, the mass of 1 mole of Oxygen is 32g. Therefore, the mass of 0.2 moles of Oxygen is 32*0.2= 6.4 g(Answer).

## What is the mass of 0.2 mole of carbon atom?

Therefore 0.2 moles of carbon = 0.2 X 12 = 2.4 g.

## How many moles are present in 2.3 gram of any?

Solution: Molecular mass of Sodium is 23 u. So, 23 g of sodium is equal to 1 mole. The number of mole in 2.3 g = 2.3 / 23 = 0.1 mole.

## What is the mass of 0.1 mole of water?

Molecular formula of water is H2O. So, adding the two we get the weight of one mole of water, which is 18g.

## What is the mass of O 2 mole of oxygen atoms?

(a) The atomic mass of oxygen (O) = 16 u. The mass of 1 mole of oxygen atoms = 16g. Hence, 0.2 mole of oxygen atom = 3.2 g.

## What is the mass of 2 mole water?

One mole of H2 O is made up of 2 moles of Hydrogen atoms and 1 mole of Oxygen atom. Mass of two moles of Hydrogen atoms = 2x 1 g/mol = 2 g/mol. Mass of one mole of water = 2 g/mol + 16 g/mol = 18 g/mol.

## What is the mass of 0.5 mole of oxygen gas?

0.5 moles of O2 weighs 16 grams.

## What is the mass of 0.50 moles of water?

Thus, the mass of 1 mole of water is 18 grams. Thus, the mass of 0.5 mole of water (H2O) is 9 grams.

## What is the mass of 0.1 mole of oxygen atom?

Mass of 0.1 mole of oxygen is = 16 * 0.1 =1.6 g.

## What is the no of molecules in 0.25 moles of oxygen?

Thus, 0.25 mole of oxygen contains 1.505×1023 molecules.
