In the above problem, the pharmacist is mixing the following:
100 ml of 49% v/v and 140 ml of 21 %v/v

Which means he is mixing:
49 ml of alcohol (present in 100 ml of 49% v/v) and 29.4 ml of alcohol (present in 140 ml of 21 %v/v)

So the final amount of alcohol in 240 ml is (49 + 29.4) 78.4 ml
Percentage would be 78.4/240 x 100 = 32.6%

We do not need to be rude to each other if we have different points or are missing something.

I got 32.666 which is 32.7%v/v.

As a rule of thumb, the final conc can only fall inbetween the two level of concentrations that make up the final conc: Dynamics.

I agree with HNKS that this is a study group kind of a thing and we shouldnt call each other names. The approach helps in getting around.

At least i know that the conc of absolute alcohol is about 95%, if the info i have seen by you guys on this problem is anything to go by, then you better prepare better or wait for oct 2010 exam, by my experience fpgee is not for just any how pharmacists

FPGEE might be hard for you. I have already passed and getting help for someone. You better check the question again with your open eyes as it is not asking for con. of absolute alcohol. You really need to study for FPGEE man, overall your calculation thinking s***s

Celestine, my reference to the 95% alcohol was to correct an impression created by FORPHARM that alcohol conc cant exceed 49%, congratulations to your passing the exams, i am never sarcastic about any knowledge i have, mind you i never said FPGEE is a difficult exam, i took it this oct.1st, all i said was that one really needs to be ready for that. Lets take a cue from the doctors forum and be polite and humble in criticism, foul words should not belong to a proffessional forum as this.
