The mass of one molecule of a substance is 4.4 × 10⁻²² g. The molar mass of this substance is approximately

A. 132 g/mol
B. 265 g/mol
✓
C. 44 g/mol
D. 88 g/mol

📝 Explanation

Molar mass = (4.4 × 10⁻²² g) × (6.022 × 10²³ mol⁻¹) ≈ 265 g/mol.

📖 Additional Information

  • 132 g/mol
  • 265 g/mol
  • 44 g/mol
  • 88 g/mol

Molar mass = (4.4 × 10⁻²² g) × (6.022 × 10²³ mol⁻¹) ≈ 265 g/mol.
