## How many molecules are there in 10g of water?

10 g of H2O cotains =6.022×102318×10 = 3.34×1023 molecules.

## What is the mass of 10 moles of water?

Number of moles=Mass/Molecular Mass. n=m/M. 10=m/18. Therefore,Mass of 10 moles of water =10×18=180 g.

## How many molecules are in 2 moles of water?

Answer: of atoms (molecules )÷ avogadro no. Since one mole is defined as 6.022 x 10^23, and there are two hydrogen per molecule, that would mean that there are exactly 12.044 x 10^23 molecules of hydrogen in one mole of water. Double that for 2 moles, and there are 24.088 x 10^23 hydrogen atoms in one mole of water.

## How many atoms are in 10 moles?

The number is 6.022 x 10^23 atoms/mol.

## How many molecules are in 9g of water?

Water has 18 grams per mole so 9 grams is 0.5 moles of water. There are6. 022* 10^23 molecules in a mole.

## How many moles are present in 10 g of H2O?

One mole of any substance weighs about the same as the molecular mass of that substance. Hence, there are [3.34times {10^{23}}] molecules of [{H_2}O] present in a 10 gram sample of [{H_2}O] .

## How many moles of molecules are there in 180g of H2O?

Moles of water =18018=10 mole.

## How many moles are in H2O?

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. Notice that the molar mass and the formula mass are numerically the same.

## What is the mass of 5 molecules of H2O?

Since one mole of water is made of two moles of Hydrogen (1.01 g/mol) and one mole of Oxygen (15.99 g/mol) its mass would be 18.01 g. Five moles of water whould have a mass of 90.05 g.

## How many h2o molecules are in 10 moles of water?

= 6.022×1024 individual water molecules.

=3.011×10^24.

## How many molecules are in 5.2 moles of h2o?

There are therefore 6.02 × 1023 water molecules in a mole of water molecules.
