Question

What is the percentage of carbon hydrogen and oxygen in ethanol?

Answer 1

carbon 52.2 percent , hydrogen 13.0 percent , oxygen 34.8 percent

Answer 2

Answer:

$\textsf{molar mass of ethanol is 46.068g}$

$\textsf{mass \: percent of carbon=} \frac{2×12.01×100}{46.068}=52.14%$

$\textsf{mass percentage of hydrogen=}$

$\textsf{mass percentage of hydrogen=} \frac{6×1.008×100}{46.068}=13.13%$

$\textsf{mass percent of oxygen=} \frac{1×16×100}{46.068}=34.73%$

hope it helps ✅✅✅.
