mass = density x volume
mass ocean H2O = 1.26 g/mL x 7.41E23 mL = ?
Then (X g NaCl/? g ocean H2O) x 100 = 2.9
Solve for X grams and convert to kg.
If the volume of ocean water 7.41*10^20 L contains 2.9 percent sodium chloride ("salt") by mass and the density of the water is 1.26 g/mL, calculate the total mass of sodium chloride. (1 ton = 2000 lb, 1 lb = 453.6 g)
Calculate the mass of sodium chloride in kg

Please explain how what the X g NaCl should be? I am not following this completely! Thanks
I got the answer for mass of H20 to be 9.337*10^23 g
I got the answer for mass of H20 to be 9.337*10^23 g
mass % = (mass solute/mass solution)*100.
You have the mass of the solution.
You want to know the mass of the solute, NaCl. Let that be X.
(x/9.34E23)*100 = ?
Solve for x = mass NaCl (in grams) and convert to kg.
