Question

Which of the following compounds is a nonelectrolyte? How many grams of potassium chloride are in 500mL of a solution which 23.5% (m/V)? Two aqueous solutions (A is 0.2 M Na_2CO_3 and B is 0.3 M KCI) are separated by a semipermeable membrane. Predict what happens. Extra Credit: The dose for the drug Fortaz is 50.mg/kg. The child is 16.5kg. An oral suspension of 5.00 %(m/V) is available. How many mL would the nurse administer to the child? Show your work on the back of the scantron and box your answer.

Explanation / Answer

18.

an electrolyte --> a substance that will dissociate in water and be able to form aquous ions.

C2H6O will NOT dissoaciate in water, it will rmeain as a neutral molecule

19.

mass = %*m ? 23.5/100*500 = 117.5 g = 118 g or C

20.

ions in first solution = i*M = 3*0.2 = 0.6

ions of second sol = i*M = 2*0.3 = 0.6

there will be no effect since ions are the same
