What is the molar mass of a compound? a) the mass in grams of 1 mole of the compound b) the number of moles in a molecular formula c) the number of atoms in 1 mole of the compound d) the number of moles in 1 g of the compound

The molar mass of a compound is The mass in grams of 1 mole of the compound (Option A)

Explanation:

Let's take ammonia as an example (NH3)

Mass of N = 14 g

Mass of H = 1 g

Molar mass of ammonia is Mass of N + (Mass of H).3

14 + 3 = 17 g/m

Ammonia is a compound that has 1 mol of N, plus 3 moles of H (see the formula)

The number of atoms in 1 mole of the compound --> This is Avogadro

the awnser is group 12
