Identify the given values: the number of moles (n) is 0.05570 mol and the mass (m) is 15.86 g.
Recall the formula for molar mass (M), which is the mass of a substance divided by the number of moles: M = m/n.
Substitute the given values into the formula: M = 15.86 g / 0.05570 mol.
Perform the division to calculate the molar mass.
Compare the calculated molar mass with the provided options to identify the correct answer.
