A solution is prepared by adding 1 mole ethyl alcohol in 9 mole water. The mass percent of solute in the solution is ____ (Integer Answer)
(Given: Molar mass in

g mol^{- 1}

Ethyl alcohol: 46, water: 18)

Answer: 22

Solution

Mass of ethanol

= 1 \times 46 = 46

g. Mass of water

= 9 \times 18 = 162

g. Total mass

= 208

mass % = \frac{46}{208} \times 100 \approx 22.1% \approx 22
