Ocean water contains 3.5 nacl by mass. what mass of ocean water in grams contains 45.8 g of nacl
Romashka-Z-Leto [24]

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):

45.8 g NaCl *\frac{100g ocean water}{3.5g NaCl}

                     = 1309 g ocean water

Therefore, 45.8 g sodium chloride is present in 1309 g ocean water.
