6. A report states that biogas is 60% methane (relative molecular mass = 16) and 40% carbon dioxide (relative molecular mass = 44) by weight. Consider 10 kg of biogas.

(a) How much methane, by weight, would you expect in 10 kg of biogas?

(b) How many moles of methane would be there in this biogas amount?

(c) How many moles of carbon dioxide would be there in this biogas amount?

(d) How many moles of biogas would there be in 10 kg of biogas?

(e) What is the pV content of 10 kg of biogas at 300 K?
