1) A solution is 9.60%(w/w) and contains 25.0 gm of salt. How much water is in the solution, and what would be a reasonable estimate of volume of solution?
2) What would be the concentration(%wt/wt) of 6.75 of salt added to 35.5g of water
3) How much water would be in a solution of 75.0g NaCl with a concentration of NaCl with a concentration of 3.2m? (atomic weight Na=23gm, Cl=35.5 gm)
4) how many mols of nitric acid would be in 1450ml of an acid solution with a density of 1.42 and assay of 70%(wt/wt)
