Question

25 ml of Hydrochloric acid is mixed with 275 g of water. Calculate (note: please give the calculations because i am asking this question 3rd time (a)the mass percent of hydrochloric acid. (b) the Volume percent of hydrochloric acid. (density of hydrochloric acid is 1.18 g/ml)

Answer 1

Answer:

Explanation:

a

mass percent = mass of solute / mass of solution *100

mass = 1.18*25

= 29.5g

mass of solution =275+29.5

= 304.5 g

mass percent = 29.5/304.5*100

= 9.68%

volume percent = volume of solute / volume  of solution *100

density of water = 1 g/cc

volume = 275 /1

= 275 ml

volume of solution = 275+25

= 300 ml

volume percent = 275/300*100

= 91.66%
