Is my answer to dilution problem right

Ok I have to prepare 250 ml of a 1.5% polyacrylamide gel. How much of the gel would I weigh to dissolve in 250 ml of buffer?

My answer is: 2.5 * 1.50g of polya. gel = 3.75g of pola. gel.

250 mL(1.5 grams of polyacr/100 mL of soln)=3.75 grams of Polyacr you would have to weigh and dissolve it in 250 ml of buffer

you got it right!
