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

Water has 18 grams per mole so 9 grams is 0.5 moles of water.

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

3.01 × 10. 6.022 × 10.

## How many moles are in 10g of water?

1 mole of water weighs 18g. 10/18 moles = 10/18 * 6 * 10^23 number of molecules = 3.33 * 10^23 molecules of water. Each molecule of water has 3 atoms, so the total number of atoms in 10g of water is 3*3.33*10^23 = 10^24.

## How many moles of oxygen are in 9g of water?

The second step is calculate the number of moles of water in 9gWe need to use the equation moles=mass/Mr 2H2 + O2 -> 2H2OMass ? 9gMr 32 18 Moles 9/18=0.53. We can now work out the number of moles of oxygen needed to make 0.5 moles of water.

## Which one has more molecules 9g of water and 9g of sugar?

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 many moles is 17g of water?

Hence 17 gm of H2O2 = 1/ 34 ×17 = 1/ 2 = 0.5moles.

## What is the number of molecules in 9g of steam?

9 gram of steam contain 3.015*10^23 H2O molecules.

## 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 H2O molecules are in 10 grams of water?

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