Answer 1

Answer:

4) All of these.

Explain:

1) Molar mass of carbon is 12g

Molar mass of oxygen is 16g

Then it is clear that molar mass of CO is 28g.

2) It is clear from the chemical equation that two obey the law of conservation of mass we need one mole of the carbon mono oxide to react with half mole of the dioxygen to give one mole of the carbon dioxide.

3) N2 = 14*2 = 28 g

CO = 12+16= 28g
