Question- Butane gas is compressed and used as a liquid fuel in disposable cigarette lighters and lightweight camping stoves. Suppose a lighter contains 3.84mL of butane (d=0.579g/mL)
Part a) How many grams of oxygen are needed to burn the butane completely?
Part b) How many moles of H2O form when all the butane burns?
Part c) How many total molecules of gas form when the butane burns completely?
Any expert is able to provide answer for this problem in very short time
