How many moles of carbon are there in a diamond weighing 2.11 g?

Interpretation Introduction

Interpretation:

The moles of carbon present in given amount of pure diamond are to be calculated.

Concept Introduction:

Mole is the unit of the amount of a substance. It relates the number of particles to molar mass.

One mole of a substance contains Avogadro number (6.022×1023) of particles. The number remains constant regardless of the nature of the substance. One mole of an atom contains 6.022×1023 atoms. One mole of a molecule contains 6.022×1023 molecules.

It also relates to the molar mass of a substance in grams. The weight of one mole of a substance is equivalent to its molar mass in grams.

To sum up, 1 mole of a substance contains 6.022×1023 particles and weighs the same as its molar mass in grams

Explanation of Solution

Given information: Diamond is a pure form of carbon and has a mass of 2.11 g .

The molar mass of carbon is
