Question 75 ptsYou want to compare a patient's measured calcium ion concentration to the normal calcium ion concentration in bloodserum. The only range you can find is 4.5 5.5 mEq/L, but the blood results show a concentration of 0.19 mmol/dL.Convert the measured calcium ion concentration from the blood results to mEq/L (to one decimal place). Do not inputunits on the Canvas answer, but they should be visible on your uploaded file.Question 85 pts189 mL of a 1.9 M solution of KBr is diluted to 668 mL. What is the new concentration of the solution (in M to 2 decimalplaces)? Do not input units on the Canvas answer, but they should be visible on your uploaded file.

Concept explainers

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
