#17
Front (Question)

Percent concentrations formula: 1. w/v % solutions: 2. v/v % solutions: 3. w/w % solutions:

Back (Answer)

• w/v % solutions: % (w/v) = weight of solute (g)/total volume of solution (mL) x 100% • v/v % solutions: % (v/v) = volume of solute (mL)/total volume of solution (mL) x 100% • w/w % solutions: % (w/w) = weight of solute (g)/total weight of solution (g) x 100%

#18
Front (Question)

How much sodium chloride should be used to prepare 2 liters of 0.85% (w/v) saline solution?

Back (Answer)

17 grams Given: solute = x solution = 2 L concentration = 0.85% solution: conc. = solute (g)/solution (mL) x 100 % 0.85 = x/2000 mL x 100% x = 0.85 x 2000 mL/100 = 17 grams

#19
Front (Question)

Formula for Molarity:

Back (Answer)

Molarity (M) = amount of solute (in moles) / total volume of solution (in mL)

#20
Front (Question)

A registered medical technologist dissolved 100 g of sodium chloride in 5 liters of distilled water. What is the molarity of the resulting solution? (MW: Na = 23 ; Cl = 35.45)

Back (Answer)

0.34 M Given: solute = 100 g —-> moles solution = 5 L M = x Solution: g —-> moles 100 g/58.45 = 1.71 moles M = 1.71 moles/5 L M = 0.34 M

#21
Front (Question)

Formula for Normality:

Back (Answer)

Normality (N) = amount of solute (in moles / total volume of solution (in L) x valence or N = M x v (valence = amount of H+ ion)

#22
Front (Question)

What is the Normality of a 200 mL solution containing 5 grams of H2SO4? (MW: H = 1; S = 32; O = 16)

Back (Answer)

0.51 N Given: Solute = 5 g Solution = 200 mL —-> 0.2 L N = x Solution: g —-> moles 5 g/98 = 0.051 moles N = 0.051 moles/0.2 L x 2 N = 0.51 N

#23
Front (Question)

What is the final concentration of a 50% solution that was diluted 1:2, 1:5 then 1:10?

Back (Answer)

0.5% Final concentration = original concentration /product of all diluting factor = 50%/2x5x10 = 0.5%

#24
Front (Question)

temperature conversions: C to F =

Back (Answer)

F = (C x 1.8) + 32
