Emergency treatment of cardiac arrest victims sometimes involves injection of a calcium chloride solution directly into the heart muscle. How many grams of CaCl2 are administered in an injection of 5.0 mL of a 5.0% 1m/v2 solution? How many milliequivalents of Ca2+?

Assuming ideal behavior, rank the solutions boiling points, 1 is lowest to 4 highest boiling point: 0.1 m CaCl2 0.1 m NaOH [Choose ] [Choose ] 0.025 m Al2(SO4)3 [Choose] 0.25 m C6H12O6 [Choose ]

An unknown mixture is known to contain only Ba(OH)2 (MW=171.34 g/mole) and NaOH (MW=40.0 g/mole).  If the mixture is known to contain 45% by mass NaOH, and 8.0 grams of the mixture is dissolved completely in 50.0 ml of solution, answer the following. c).If 10.0 ml of a 0.2 M solution of Na2SO4 was added to the 50.0 ml solution, what would be the final concentration of Na+ in solution.

how many grams of sr(no2)2 are needed to make 200 ml of 0.300M solution of sr(no2)2
