Stoichiometric amounts of C7H14 and oxygen are sealed in a flask that has a volume of 1.500 L. Pressure is measured and is 28.476861 atm at 297.15 K. The vapor pressure of the water is 0.02947 atm at 297.15 K. How many grams of each product are formed and with how many grams of C7H14 did you start with? R = 0.0820578(L)(ATM)/(K)(mol)
