= 9.54 gm of Triamcinolone grams of HCl:

The percentage of Triamcinolone in the final = 274.28 gm
mixture: 1.25 gm/ml = 219.42 ml HCl acid

100 x 9.54 1210. (b) 0.025 min
-1
= = 2.1% w/w
454
For the first order kinetic:
1207. (a) The osmolarity of Sodium bicarbonate
solution can be calculated as follows: 2.303 Co
k = log ℎ
t C
gm
mOsm Weight ( L ) x No. of Species x 1000
= Co = original concentration = 500
L Molecular weight C = concentration at time t = 50
t = time = 90 minutes
25gm/100cc = 250gm/1000cc
2.303 500
A number of species = 2 k = 90 log 50

250 2 1000
= = 5952.38 / k = 2.303 log10
84 90

1208. (b) 510 calories 2.303
−
k = 90 = 0.025
Though technically a kilocalorie is 1000 calories, the
American "calorie" that is listed on nutrition labels 1211. (d) 480cc, 20% sodium bicarbonate solution
is synonymous with the kilocalorie included on contains:
European labels.
= 480 x 0.2
Therefore, each gram of dextrose provides 3.4 = 96 gm of sodium bicarbonate
calories or kilocalorie. = 96000 mg of sodium bicarbonate

Calories provided by 500cc D30W: Molecular weight
Equivalent weight = Number of valence
500 x 30 x 3.4
= = 510 calories or kcal
100 84
Equivalent weight = 1 grams/equivalent
1209. (c) The amount of HCl acid is required to
prepare 1 gallon, 2.5% HCl is as follows: 1 equivalent = 84 gm sodium bicarbonate
1 mEq = 84 mg sodium bicarbonate
3840 x 2.5
= = 96 grams HCl acid
100 MilliEquivalents = Weight in milligrams
Equivalent weight
The purity of HCl acid is 35% w/w, so to get
96 grams of pure HCl, we need: + 96000
mEqs of Na = 84 = 1142.85
96 x 100
= = 274.28 grams HCl acid
35 1212. (c) TPN solution should provide 55% of 1500
non-protein calories as dextrose, therefore:
The volume of HCl acid is needed to prepare 274.28
