1. The problem statement, all variables and given/known data The total volume of seawater is 1.5 10^21 L. Assume that seawater contains 3.1 percent sodium chloride by mass and that its density is 1.03 g/mL. Calculate the total mass of sodium chloride in kilograms and in tons. (1 ton = 2000 lb; 1 lb = 453.6 g) 2. Relevant equations D=m/v m=d x v 3. The attempt at a solution 1.5 x 10^21 x .031= 61324931.65 g/L 61324931.65x .001=61324.93165kg ?
