Using proportions, the number of milligrams of sodium chloride that are contained in 1 liter of 0.6% sodium chloride solution is:
C. 6000 mg.
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
The amount of liters of sodium is given by:
A = 0.006 x 1 = 0.006 liters.
Each liter has 1,000,000 milligrams, hence the amount of milligrams is given by:
Am = 0.006 x 1,000,000 = 6000 mg.
Which means that option C is correct.
