Question

the mass by mass percentage of a solution is 20%. find the mass of the solute dissolved in 500g of solution​

Answer 1

`m_(solute)=100g`

Step-by-step explanation:

Hello,

In this case, by considering the mathematical definition of by mass percentage of a solute as shown below:

`\%m/m=(m_(solute))/(m_(solution))*100\%`

We are able to compute the mass of the solute in a 20% solution having 500 g of solution as follows:

`m_(solute)=(m_(solution)*\%m/m)/(100\%) =(500g*20\%)/(100\%)\\ \\m_(solute)=100g`

Best regards.
