Verified step by step guidance1
Understand that molar mass is defined as the mass of one mole of a substance, typically expressed in grams per mole (g/mol).
Use the formula for molar mass: \( \text{Molar Mass} = \frac{\text{Mass}}{\text{Moles}} \). In this problem, the mass is given as 15.86 g and the moles as 0.05570 mol.
Substitute the given values into the formula: \( \text{Molar Mass} = \frac{15.86 \text{ g}}{0.05570 \text{ mol}} \).
Perform the division to calculate the molar mass. This will give you the molar mass of diazepam.
Compare your calculated molar mass with the provided options to identify the correct answer.
