Mass percentage of sodium chloride(NaCl) in ocean waters = 3.5 %
That means 3.5 g sodium chloride(NaCl) is present for every 100 g of ocean water.
The given mass of sodium chloride(NaCl) is 45.8 g
Calculating the mass of ocean waters that would contain 45.8 g sodium chloride(NaCl):
[tex]45.8 g NaCl *\frac{100g ocean water}{3.5g NaCl}[/tex]
= 1309 g ocean water
Therefore, 45.8 g sodium chloride is present in 1309 g ocean water.
