The intreval volume of a clorimeter was1.12L. A sample of gas of 1.863g of nonae was added, and the closed calorimeter then had added oxygen until the pressure was 10.0atm na dht etemp was 23.1 C.Write the full balanced equation of the combustion of the nonae in the calorimeter.

Ho many moles of oxyen were present before combustion? and how many grams of oxygen were formed after combustion if the nonane was completyl consumed? need help with the work not the answer.
