The average adult human male has a total blood volume of 5.0 L. If the concentration of sodium ion in this average individual is 0.131 M, what is the mass of sodium ion circulating in the blood? Express your answer using two significant figures.
Answer : The mass of sodium ion is,
Explanation : Given,
Concentration of ion = 0.131 M
Volume of solution = 5.0 L
Molar mass of ion = 23 g/mole
Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.
Formula used :
Now put all the given values in this formula, we get:
Therefore, the mass of sodium ion is,
