To do this you need to work out formula mass, the weight of 1 mole of any chemical.
Waters formula is H2O so write;
2H
O
Then find the relative Atomic Mass of these elements
Hydrogens weigh is 1
Oxygen is 16
2x1
1x16
then add them together
2+16 = 18
that is the weight in grams of 1mole
so 36g is the weight of 2moles
