Question

This is the chemical formula for methyl acetate: CH32CO2. Calculate the mass percent of hydrogen in methyl acetate. Round your answer to the nearest percentage. %

Answer 1

Answer: The mass percent of hydrogen in methyl acetate is 8 %

Step-by-step explanation:

The given chemical formula of methyl acetate is
`CH_3COOCH_3`

To calculate the mass percentage of hydrogen in methyl acetate, we use the equation:

`\text{Mass percent of hydrogen}=\frac{\text{Mass of hydrogen}}{\text{Mass of methyl acetate}}* 100`

Mass of hydrogen = (6 × 1) = 6 g

Mass of methyl acetate = [(3 × 12) + (6 × 1) + (2 × 16)] = 74 g

Putting values in above equation, we get:

`\text{Mass percent of hydrogen}=(6g)/(74g)* 100=8.10\%=8\%`

Hence, the mass percent of hydrogen in methyl acetate is 8 %
