Question

How many moles in 10g of water

Answer 1

hope it helps you out dude

Answer 2

Here is detailed calculation for clarity.

1 mole of water weighs 18g.

1 mole of water contains 6*10^23 water molecules (Avagadro’s Number)

10g of water = 10/18 moles of water

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.

Note these are using approximated values, so the final result is also approximate, but should be pretty close.
