I can't make heads or tails of the question. No caps to begin a sentence, no periods, no question marks. I'll look at it again if you want to do it right.
Calculate the pressure in atm of a balloon filled with 7.50g of helium gas if the balloon's volume decreases to 7.50L. Suppose the balloon's pressure and volume are originally 799 mmHg and 15.0L.
P1V1 = P2V2
