Question

A solution is prepared by dissolving a

certain amount of solute in 500 g of
water. The percentage by mass of a
solute in a solution is 2.38. Calculate the
mass of solute​

Answer 1

solution = solute + solvent

% mass of solute:

`\tt (mass~solute)/(mass~solution)* 100\%`

for % mass of solute = 2.38%, then mass of solute:

`\tt =2.38\%* 500~g=\boxed{\bold{11.9~g}}`

Answer 2

119g

Step-by-step explanation:

Just multiply

2.38% of 500 =

119 g
