Question

The number of gram atoms present in 288g of sulphur is ?

Answer 1

$molar \: mass \: of \: sulphur = 32u \\ given \: mass = 288g \\ number \: of \: moles = \frac{288}{32} = 9 \\ number \: of \: atoms \: of \: \\ sulphur = 9 \times 6.023 \times {10}^{ - 23} \\ = 5.4207 \times {10}^{ - 22}$
