## Calculate the molar mass of each of the following compounds:(a) Fe(C6H11O7)2, iron(II) gluconate, a dietary supplement(b) CH3CH2CH2CH2SH, butanethiol. has a skunk-like odor(c) C20H24N2O2, quinine, used as an antimalarial drug

(a)

Interpretation Introduction

Interpretation:

For the given molecules, the molar masses are needed to be calculated.

Concept introduction:

• Molar mass of a molecule can be calculated from its molecular formula by taking the sum of atomic masses of all the elements present in it.

### Explanation of Solution

The molecular formula of iron (II) gluconate is Fe(C6H11O7)2, so the molar mass of iron (II) gluconate is,

1×55.845(Fe)+12×12.01(C)+22×1

(b)

Interpretation Introduction
