Butane gas is compressed and used as a liquid fuel in disposable cigarette lighters and lightweight camping stoves. Suppose a lighter contains \( 2.55 \mathrm{~mL} \) of butane \( (d=0.579 \mathrm{~g} / \mathrm{mL}) \). (a) How many grams of oxygen are needed to burn the butane completely? \( \mathrm{g} \mathrm{O}_{2} \) (b) How many moles of \( \mathrm{H}_{2} \mathrm{O} \) form when all the butane burns? moles \( \mathrm{H}_{2} \mathrm{O} \) (c) How many total molecules of gas form when the butane burns completely? \( \times 10 \) molecules of gas (Enter your answer in scientific notation.)
