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

Answer:

119g

Explanation:

Just multiply

2.38% of 500 =

119 g

Answer 2

solution = solute + solvent

% mass of solute:

$\tt \dfrac{mass~solute}{mass~solution}\times 100\%$

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

$\tt =2.38\%\times 500~g=\boxed{\bold{11.9~g}}$
