## How many grams of H2O are present in 0.2 mole?

2 moles of H2O gets 36 grams.

## What is the mass of 0.2 mole of H2O?

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

## How many gram of H2O are present in half mole of it?

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

## How many grams H2O is present in 0.25 moles of it?

1 mole of water weighs equal to the molecular mass of water. Thus the amount of present in 0.25 mole of it​ is 4.5 grams.

## What is the mass of 2 mole of water *?

If we have one mole of water, then we know that it will have a mass of 2 grams (for 2 moles of H atoms) + 16 grams (for one mole O atom) = 18 grams.

## How many grams of H2O are present in?

The average mass of one H2O molecule is 18.02 amu. The number of atoms is an exact number, the number of mole is an exact number; they do not affect the number of significant figures. The average mass of one mole of H2O is 18.02 grams.

## What is the mass of 0 2 mole of oxygen atom?

(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 mass is 0.5 mole water?

Mass of 0.5 mole of water is 9g.

## What is the mass of 2 A 0.2 mole of oxygen atoms B 0.5 mole of water molecules?

-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.

## How many water molecules are there in 1 mole of H2O?

A mole (mol) is the amount of a substance that contains 6.02 × 10 23 representative particles of that substance. The mole is the SI unit for amount of a substance. Just like the dozen and the gross, it is a name that stands for a number. There are therefore 6.02 × 10 23 water molecules in a mole of water molecules.

## How many liters are in 1 mole of H2O?

One mole of water has a mass of 18 grams and volume of 18 milliliters or 0.018 liters. How much is a mole of water? A mole of water is Avogadro’s number of water molecules.

## What is the molar mass of c6h8o6?
