Work Step by Step
We have 3.5% NaCl by mass and 254 g of sea water. Accordingly, the conversion factor is: 3.5g NaCl/100 g sea water. Calculating the mass of NaCl by using the conversion factor. = (254 g sea water)x(3.5g NaCl/100 g sea water.) = 8.89g NaCl Hence the mass of sodium chloride is 8.9g.
