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 units (amu) of one molecule of a compound is equivalent to the mass in grams of one mole of that compound.

Step by step solution

01

Understand the Concept of the Mole

A mole is a unit in chemistry that helps to measure the amount of a substance. It's a method that allows scientists to convert between the atomic/molecular mass and the amount in grams. One mole of any substance contains \(6.022 \times 10^{23}\) representative particles (atoms, molecules, etc.), a figure known as Avogadro's number.
02

Relate Mass in amu of One Molecule and Mass in Grams of One Mole

The molecular weight/molar mass is the sum of the atomic weights of the atoms in a molecule. It describes the mass of one molecule in atomic mass units (amu). It also indicates the mass of one mole of the compound in grams. This means that the mass in amu of one molecule of a compound is numerically equivalent to the mass in grams of one mole of that compound.
03

Formulate the Relation in a Grammatically Correct Sentence

Upon obtaining the numerical relationship derived in Step 2, one can express this as follows: 'The mass of one molecule of a compound, measured in atomic mass units, is equivalent to the mass of one mole of that compound, measured in grams.'
