Chapter 6, Problem 48A
Interpretation Introduction

Interpretation :

Molecular formula of the compound with empirical formula CH4O and molar mass approximately 192 g must be found out.

Concept Introduction :

Empirical formula of a molecule is the smallest unit which is repeated in the molecule.

Molecular formula of a compound is the representation of the molecule with the number of different atoms present in the molecule.

Molecular formula =empirical formula×n where n is any positive integer like 1, 2, 3 and so on.

Answer to Problem 48A

The molecular formula is C6H24O6.

Explanation of Solution

The molecular formula can be found from the empirical formula using the following relationship.

Molecular formula =empirical formula×n where n is any positive integer like 1, 2, 3 and so on.

Molar mass of CH4O=(12+4×1+16)g=32 g.

Molar mass of the compound is approximately 192 g.

Now Molecular formula= (CH4O)n .

Thus 192= (CH4O)n or n=19232=6 .

Thus molecular formula is (CH4O)6=C6H24O6.

Conclusion

Molecular formula of the compound is C6H24O6.
