## What is the mass of 0.2 moles of oxygen?

3.2 grams

-To calculate the mass of 0.2 moles of oxygen atom we should know the mass of a single atom of oxygen that is 16. -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 the mass of a mole of O2?

32 g

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 0.1 mole of oxygen atom?**

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

### What is the mass of 0.5 moles of oxygen?

0.5 moles of O2 weighs 16 grams.

### What is the mass of 0.5 moles?

Mass of 0.5 mole of water is 9g.

**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).

## How many grams is 2 moles of oxygen?

63.9976 g

Just multiply 2 by 31.9988 g because there are two moles of oxygen. So, the answer is 63.9976 g ..

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

The mass of 1mole of water =18gms. Than, the mass of 0.2moles of water=x. Now x=18×0.2=3.6gms.

**What is the mass of 0.5 mole of water molecules Class 9?**

9g

Mass of 0.5 mole of water is 9g.

### What is the mass of 0.2 mole of h2?

Weight of 0.2 mole H2 gas = 2(Mol. Mass) x 0.2 = 0.4 g.

### What is the no of molecules and no of atoms in 0.5 moles of oxygen?

=3.011×1023×2=6.022×1023.

**How many grams are in 1 mole of oxygen?**

molecular weight of Oxygen or grams The molecular formula for Oxygen is O. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Oxygen, or 15.9994 grams .

## How many atoms are in 1 mole of oxygen?

1 Molecule oxygen consists of 2 atoms . 1 mole O2 = 6.02. 10 23 molecules (number of Avogadro). thanked the writer. blurted this. There are 2 molecules in oxygen (02).

## How do you calculate molar volume of oxygen gas?

The molar volume of the oxygen was calculated by dividing its corrected volume by the moles of oxygen. With this, the computed molar volume of O2 from the experiment is L/mol.

**How do you calculate the mass of a molecule?**

No matter how large or small the molecule, the procedure for calculating its molecular mass is the same. You look up the atomic mass of each of the elements in the formula, multiply it by the number of atoms of that element in the compound and add it to all the others. This gives you the mass, in grams, of one mole of the molecule.
