The true statement regarding the masses of a sample of copper and a sample of aluminum with equal number of atoms should be identified. Concept Introduction: According to Avogadro’s number, one mole of any substance contains same number of atoms which is 6.023 × 10 23 . However, molar mass of one substance is different from another substance. For a substance, number of moles, mass and molar mass can be calculated as follows: n = m M Here, n is number of moles, m is mass and M is molar mass.

Chapter 8, Problem 94AP
Interpretation Introduction

Interpretation:

The true statement regarding the masses of a sample of copper and a sample of aluminum with equal number of atoms should be identified.

Concept Introduction:

According to Avogadro’s number, one mole of any substance contains same number of atoms which is 6.023×1023.

However, molar mass of one substance is different from another substance.

For a substance, number of moles, mass and molar mass can be calculated as follows:

n=mM

Here, n is number of moles, m is mass and M is molar mass.
