What is the molar mass of compound represented by following structure formula?

Options

  1. A36 ~g ~mol ⁻¹
  2. B46 ~g ~mol ⁻¹
  3. C22 ~g ~mol ⁻¹
  4. D32 ~g ~mol ⁻¹

Correct answer

B. 46 ~g ~mol ⁻¹

Step-by-step solution

The line-angle structure represents ethanol ( C₂H₆O ). Carbon atoms occur at vertices and line endpoints, with hydrogen atoms implied to satisfy carbon's tetravalency. The formula gives a molar mass calculation: M = 2 12.01 + 6 1.008 + 1 16.00 = 24.02 + 6.048 + 16.00 = 46.068 g mol⁻¹ This value approximates to 46 g mol⁻¹ , matching option B .
