Rx Apomorphine Hydrpchloride...................1%

Sodium chloride..................................q.s

Purified water ad.................................100 mL

Make isoton. sol. Tf 1% of Apomorphine Hydrpchloride= 0.08 C

Answer 1

Answer:-0.76 grams of sodium chloride is required

In a simple way

E value of amomorphine hydrochloride=0.14

1%amomorphine hydrochloride =1%=1/100*100= 1 gr

so 0.14*1=0.14grams of Nacl represented by amomorphine hydrochloride.

0.009 gr of sodium chloride basical weight

so 100*0.009=0.9 gr of Nacl in 100 ml of isotonic solution.

substract amount of Nacl represented by amomorphine hydrochloride from amount of Nacl alone

so 0.9-0.14=0.76

Answer=0.76 grams
