A balloon contains 2.71 g of SO2(g) and 2.04 g of CH.(). Calculate the partial pressure of each gas in the balloon if the total pressure of the entire gas sample in the balloon is 6.00 atm.

In a laboratory, 1.55mg of an organic compound containing carbon, hydrogen, and oxygen is burned for analysis. this combustion resulted in the formation of 1.45mg of carbon dioxide and .89 mg of water. what is the empirical formula for this compound?
