i hate life
Life is 2 miserable
i hate pharmaceutical calculations
i hate organic chemistry
i hate anatomy
but i love pharmacy

1. A formula for 1250 tablets contains 3.25 grams of diazepam. How many grams of diazepam should be used in preparing 350 tablets?

2. If 100 capsules contain 500 ng of an active inredients. how many mg of the ingredient will 48 capsules contain?

dbah makasakit buntuk...hahhhhhhhhhhhhhhhh
