Explanation / Answer

A)

30% NaCl to mass of NaCl --> we need 30 g of NaCl / 100 g of solution

so grams of solutino cancel each other and g of NaCl is left

b)

simply multiply by given volume of solution * 8 mL of ethanol / 100 mL of solution

since we need mL of ethanol

c)

14 g of fructose / 100 mL of solution * X mL of solution = Y grams of fructose

d)

if we need Liters of solution

M = mol/V

V = mol/M

we need

to divide by molarity --> X mol of HBr * 1 Liter of solution / 5 mol of HBr = Liter of solution
