Thimerosal is an organic compound (gram molecular mass = 404.8 g/mol) used to inhibit bacterial growth. A .100%solution of thimerosal is sometimes used as an antiseptic. Assume that this solution has a density of 1.00 g/mL.

A. how many grams of thimerosal are found in .500 g of .100% solution?

B. how many grams of thimerosal must be mixed with 25.0 g of water to make a .100% solution?

C. what mass of thimerosal must be mixed with 25.0 g of wwater to make a 0.100% solution?

D. how many grams of thimerosal are required to make 75.0 mL of .100% solution?

E. what volume of .100% solution contains 0.750 g of thimerosal?
