## How many moles are in 9g of H2O?

Originally Answered: What is the number of moles present in a 9 gram of H2O? The molecular weight of water is 18. So if you have 9g of water, you would have 9/18 = 0.5 moles.

## How many moles are in 8g of H2O?

The atomic weight of hydrogen atoms is 1, but the molar mass of diatomic H2 is 2 g/mol. Therefore, 8 g of H2 is 4 moles. Therefore you will form 4 moles of water.

## How many molecules are present in 9g of h20?

= 3. 011 x 10^23.

## How many moles of are there in 1000 g of water?

Now 18g of H20 is equivalent to 1 mole. Hence, 1000g of it would be equal to 1000/18 moles. This comes out be 55.55 moles.

## How many moles are in H2O?

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. This is stated: the molar mass of water is 18.02 g/mol.

## How many moles is 135g of water?

Suppose that you have 5.00 g of KNO3. The molar mass of KNO3 is (39.1 +14.0 + 3×16.0) g/mol = 101.1 g/mol. Therefore there are 5.00 g / 101.1 g/mol = 0.0495 mol of KNO3. n = the number of moles of a compound.

## How many molecules are present in 1g of water?

or 1 g of water contains (6.022 x 1023)/ 18 water molecules and the number comes out to be 3.3455 x 1022. So the number of water molecules present in 1 g of water is 3.3455 x 1022.

## How do I calculate moles?

How to find moles?

1. Measure the weight of your substance.
