Answer:

14 % (to the nearest percentage)

Explanation:

We must first obtain the molar mass of diethyl ether rom its molecular formula,  C4H10O.

relative atomic mass of carbon =12, hydrogen =1 oxygen -16

Hence we have;

(4*12) + (10*1) +16 = 48 + 10 + 16 = 74g/mol

mass percent = total mass of hydrogen/ molar mass of compound * 100

% by mass of hydrogen = 10/74 * 100 = 14 % (to the nearest percentage)
