Question

A solution is prepared by dissolving a certain amount of solute in $500g$ of water. The percentage by mass of solute in the solution is $2.38$.

Calculate the mass of the solute.

Answer 1

Percentage by mass of the solute in solution is $2.38$%

Therefore, for every 100g of the solution $2.38$g is solute and $97.62$g.

Now for $500$ g of solution mass of solute $=5\times 2.38=11.9g$
