3 0

you are given the number of moles, from the given formula you can get the molar mass which is 12.00g/mol + 16 g/mol =28 g/mol. using the formula n=m/Mr rearrange the formula and make m subject, you thn have m=nMr therefore 7.60x 1021 mol x 28g/mol= m

m = 217268.8 g, you will notice that mol cancel out each other leaving you with g.

now convert g to litres

1 litre is equal to 1000 grams therefore

217268.8g x 1l/1000g = 217,269 litres
