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)
