Question

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

Answer 1

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

Step-by-step 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
