Chapter 28: Problem 11

Use a grammatically correct English sentence to describe how the mass in amu of one molecule of a compound is related to the mass in grams of one mole of that compound.

Short Answer

Expert verified
The mass in atomic mass unit (amu) of one molecule is numerically equivalent to the mass in grams of one mole of that compound.

Step by step solution

01

Understand Molecular mass

The molecular mass of a substance (also known as molecular weight) is the sum of the atomic masses (in atomic mass unit, amu) of all the atoms in a molecule.
02

Understand Moles and Avogadro's number

A mole is a unit used in chemistry that equals to Avogadro's number, which is \(6.022 \times 10^{23}\) entities (these could be atoms, molecules, ions etc.). It means that one mole of any substance contains \(6.022 \times 10^{23}\) of these entities.
03

Relation between amu and gram for one mole

The mass of one mole of a substance in grams is numerically equal to the molecular mass of the substance in amu. This implies that the molecular mass of a molecule in amu is equivalent to the mass in grams of one mole of that molecule.
