Find the mass of 1 molecule of H ₂ SO ₄ in grams.

Options

  1. A1.605 10⁻²² g
  2. B1.665 10⁻²² g
  3. C1.647 10⁻²² g
  4. D1.627 10⁻²² g

Correct answer

D. 1.627 10⁻²² g

Step-by-step solution

Molar mass of H ₂ SO ₄ is 2(1) + 32 + 4(16) = 98 g/mol Number of molecules in 1 mole = 6.022 10²³ Mass of 1 molecule = 98 6.022 10²³ g Mass of 1 molecule = 16.27 10⁻²³ g = 1.627 10⁻²² g Answer: 1.627 10⁻²² g
