Question

A fat is composed, in part, of long chains of carbon and hydrogen. This fat as a molecular

mass of 847 grams/mole and an empirical formula of C9H170. Determine the molecular
formula.

Answer 1

`C_(54)H_(102)O_6`

Step-by-step explanation:

Hello!

In this case, since the molar mass of the empirical formula is:

`MM_(empircal)=9*12.01+17*1.01+16.00=141.26g/mol`

Thus, the ratio of the molecular to the empirical formula is:

`(847g/mol)/(141.26g/mol) =6.0`

Thus, the molecular formula is six times the empirical formula:

`C_(54)H_(102)O_6`

Best regards!
