# Using the average atomic masses given inside the front cover of the text, calculate how many moles of each substance the following masses represent.l type='a'>4.21 g of copper(II) sulfate7.94 g of barium nitrate1.24 mg of water9.79 g of tungsten1.45 lb of sulfur4.65 g of ethyl alcohol, C 2 H 5 OH i>12.01 g of carbon

Interpretation Introduction

(a)

Interpretation:

Number of moles of each substance the following masses represent should be calculated.

Concept Introduction:

The molar mass, also known as molecular weight, is the sum of the total mass in grams of all the atoms that make up a mole of a particular molecule.

Molar mass=Mass of the sample in gramsNumber of moles

Number of moles=Mass of the sample in gramsMolar mass.

Explanation

Molar mass of CuSO4 = { 63.55 + 32.07 + (3 × 16.00)} g/mol = 143
