Question

A sample comprised of C, H, and O was found to contain 38.70% carbon and 9.75% hydrogen.What is the empirical formula for this compound? If the molar mass is 62.08 g/mol is the derived formula the empirical or molecular formula?

Expert Solution

Step 1

Given,

A hydrocarbon comprised of C, H, and O was found to contain 38.70% carbon and 9.75% hydrogen.

Therefore, percent of oxygen= 100% - (38.70% + 9.75%)

= 100% - 48.45%

Percent of oxygen= 51.55%
