1.00 × 10²⁴ molecules of water have a mass of 29.9 g.
First, we will convert 1.00 × 10²⁴ molecules to moles using Avogadro's number: there are 6.02 × 10²³ molecules in 1 mole of molecules.
[tex]1.00 \times 10^{24} molecule \times \frac{1 mol}{6.02 \times 10^{23} molecule } = 1.66 mol[/tex]
The molar mass of water is 18.02 g/mol. The mass corresponding to 1.66 moles of water is:
[tex]1.66 mol \times \frac{18.02g}{mol} = 29.9 g[/tex]
1.00 × 10²⁴ molecules of water have a mass of 29.9 g.
