Answer:
62%
Explanation:
Consider that a and g be the amount of drug having molecular weight =369 and sugar having molecular weight 342 respectively.
Now we are given that;
a+b=1.0 …(1)
According to gas equation
PV=(n1+n2)RT
0.80 × (100 /1000) = [a / 369 + b/342]×0.0821×300
342a+369b=358.66 …(2)
Solving eq 1 and eq2 we get
a=0.617g
b=0.383g
Hence the percentage of drug would be 0.6171×100 = 62%
