how much sugar is dissolved in 500 grams of a solution if the solution is 70 percent sugar by mass?

Also,

What is the concentration of a solution that contains 45 grams of sugar in 500 grams of solution?

thank you

70% of 500 g, since the 500 g "solution" is the sum of both sugar and water.

For the second problem,

[mass sugar/mass solution]*100 = percent by mass.
