Best answer: How many moles are in 9g of water?

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.
