You are given a 1.275 ✕ 10^{3} L sample of saltwater that contains 3.40 percent sodium chloride by weight. If the density of the water is 1.16 g/mL, calculate the total number of grams of sodium chloride in the sample. Be sure to answer using the correct number of significant figures. (Hint: the 3.40 percent means that there are 3.40 g of sodium chloride for every 100.0 g of saltwater)
