Answer:

Approximately 53.3  %.

Explanation:

Molar mass of C2H4O2

= 2 * 12.011 + 4 * 1.008 + 2 * 15.999

=  60.052

% oxygen = (31.998* 100) / 60.052 = 53.28 %

The approximate percent mass of oxygen would be  53.28%.

What is Oxygen?

Oxygen is known as the chemical investment with generally the symbol O and the atomic number as 8.

Molar mass of C2H4O2 would be as

= 2 * 12.011 + 4 * 1.008 + 2 * 15.999

=  60.052

% oxygen = (31.998* 100) / 60.052 = 53.28 % is the appropriate answer.

Therefore Percent mass would be highly reactive.
