this is the chemical formula for methyl acetate: (ch₃)₂co₂. calculate the mass percent of carbon in methyl…

Explanation:

Step1: Determine atomic masses

Atomic mass of C = 12 g/mol, H = 1 g/mol, O = 16 g/mol.

Step2: Calculate molar mass of methyl - acetate

In $(CH_3)_2CO_2$, there are 3 C atoms, 6 H atoms and 2 O atoms. Molar mass $M=(3\times12)+(6\times1)+(2\times16)$ $M = 36 + 6+32$ $M=74$ g/mol.

Step3: Calculate mass of carbon in methyl - acetate

Mass of carbon $m_C=3\times12 = 36$ g/mol.

Step4: Calculate mass percent of carbon

Mass percent of carbon $=\frac{m_C}{M}\times100%=\frac{36}{74}\times100%$ $\approx49%$

Answer:

49%
