Question

unit 3 chem l test 2526
what is the molar mass of iron (fe)?
26 g/mol
8 g/mol
55.845 g/mol
71.0 g/mol

Explanation:

Step1: Recall molar - mass concept

The molar mass of an element is numerically equal to its atomic mass in grams per mole.

Step2: Find iron's atomic mass

The atomic mass of iron (Fe) from the periodic table is approximately 55.845 u. So its molar mass is 55.845 g/mol.

Answer:

C. 55.845 g/mol
