Ocean water contains 3.5% NaCl by mass. What mass of ocean water in grams contains 45.8 g of NaCl?
Solution: Here, we are going to calculate the mass of ocean water containing 45.8 g of NaCl.
Step1:
The mass percentage of a component of a solution is defined as:
Mass of the component in the solution
Mass % of a component = ----------------------------------------------------- × 100 ---(1)
Total mass of the solution
Step2:
Given, mass % of NaCl = 3.5 %
Mass of...
