Answer to Question #317102 in General Chemistry for connor

Question

An elevated level of sodium ions in the blood would be 0.155 mol L^-1 and would be cause for concern. The average adult female has a total blood volume of 4.70 L. Calculate the total mass of sodium ions present when this concentration is found, assuming a blood volume of 4.70 L. 

Answer 1

elevated level = 0.155 mol L^-1

Average volume = 4.70 L

total moles = 4.70*0.155

= 0.7285 moles.

mass = moles*molecular mass

Molecular mass of soudim = 23g

Therefore Mass of sodium ions present = 0.7285*23

16.7555g
