The answer would be
A. the mass in grams of one mole of a substance
Answer: Option (a) is the correct answer.
Explanation:
Molar mass is defined as the mass in grams of one mole of a substance.
Mathematically, Molar mass = [tex]\frac{mass in grams}{moles of substance}[/tex]
For example, molar mass of 1 mole of [tex]CH_{4}[/tex] molecule will be calculated as follows.
Molar mass of [tex]CH_{4}[/tex] = [tex]mass of carbon atom + 4 \times mass of hydrogen atom[/tex]
= [tex]12 + 4 \times 1[/tex]
= 16 g
Therefore, 1 mole of [tex]CH_{4}[/tex] molecules has a molar mass of 16 g.
