Solution Composition - Molarity - Mass Of Sodium Ions Circulating In Blood

Solutions are homogeneous mixtures. Solutions consist of solutes and solvents (the more voluminous substance into which the solute dissolves). Solution concentration measures the amount of solute per liter of the solvent. Molarity is a commonly used measure of solution concentration.

The total blood volume in an average adult human is 5 Liters.
What is the mass of sodium ion circulating in the blood of the average adult human, if the concentration of sodium ion in this average person is 0.135 M?

The strings: S7P1A15 (containership - mass).

The math:
Pj Problem of Interest is of type containership (mass).

0.135 M of sodium ion = 0.135 mol/ L of sodium ion
So, 5 L contains 0.675 mol
molar mass of sodium = 23 g
So, O.675 mol sodium ion = 23(0.675) = 15.5 g of sodium ion.
