## Using the average atomic masses given inside the front cover of this book, calculate the mass in grams of each of the following samples.l type='a'>2.17 moles ot germanium, Ge4.24 mmcl of Iead(II) chloride (1 mmol = 1/1000 moI)0.0971 mole of ammonia, NH 3 :math> 4.26 × 10 3 moles of hexane, C 6 H 14 i>1.71 moles of iodine monochloride, ICI

Interpretation Introduction

(a)

Interpretation:

Number of moles of substance should be calculated.

Concept Introduction:

For a substance, number of moles is related to mass and molar mass of the substance as follows:

n=mM

Here, m is mass of substance in g and M is molar mass of substance in g/mol.

Thus, from number of moles, mass can be calculated as follows:

m=n×M.

### Explanation of Solution

Molar mass of Ge =

72.59 g/mol

Mass of the sample in grams = Number of moles × Molar mass

= 2

(b)

Interpretation:

Number of moles of substance should be calculated.

Concept Introduction:

For a substance, number of moles is related to mass and molar mass of the substance as follows:

n=mM

Here, m is mass of substance in g and M is molar mass of substance in g/mol.

Thus, from number of moles, mass can be calculated as follows:

m=n×M.
