18 g of water contains 6.022 × 10^23 molecules
4.5 g of water contains “x” molecules
x = (4.5 × 6.022 × 10^23) / 18
x = 1.50 × 10^23 molecules
∴ 4.5 g of water contains 1.50 × 10^23 molecules
4.5 g of water contains “x” molecules
x = (4.5 × 6.022 × 10^23) / 18
x = 1.50 × 10^23 molecules
∴ 4.5 g of water contains 1.50 × 10^23 molecules
