1) Calculate the maximum mass of methanol that could be made from 14g of carbon monoxide.

1) Calculate the maximum mass of methanol that could be made from 14g of carbon monoxide.
CO(g) + 2H2(g) —> CH3OH(g)
Relative formula masses (Mr): CO = 28, CH3OH= 32

2) “The beginning of this question talks about airbags.”
The mixture of chemicals contains sodium azide (NaN3) when decomposes on heating to form sodium and nitrogen.
2NaN3 —> 2Na + 3N2

A typical airbag contains 130g of sodium azide.
Calculate the mass of nitrogen that would be produced when 130g of sodium azide decomposes.
Relative atomic masses (Ar) N = 14, Na =23

3) What is the mass of one mole of iron (II) sulfate? Remember to give the unit (g)
