Volume occupied by one molecule of water (density .=1 ~g ~cm^ -3 )...

Volume occupied by one molecule of water (density =1 g cm−3)\left.=1 \mathrm{~g} \mathrm{~cm}^{-3}\right) is

Options

  1. A5.5×10−23 cm35.5 \times 10^{-23} \mathrm{~cm}^3
  2. B9.0×10−23 cm39.0 \times 10^{-23} \mathrm{~cm}^3
  3. C6.023×10−23 cm36.023 \times 10^{-23} \mathrm{~cm}^3
  4. D3.0×10−23 cm33.0 \times 10^{-23} \mathrm{~cm}^3

Correct answer

D. 3.0×10−23 cm33.0 \times 10^{-23} \mathrm{~cm}^3

Step-by-step solution

Volume of 1 molecule of H2O=18 g6.02×1023×1 g/cc\mathrm{H}_2 \mathrm{O}=\frac{18 \mathrm{~g}}{6.02 \times 10^{23} \times 1 \mathrm{~g} / \mathrm{cc}} \cong 3.0 ×\times10^{-23} \mathrm{~cm}^3
