Oxides of nitrogen are pollutant gases which are emitted from car exhausts.
in urban traffic, when a car travels one kilometre, it releases 0.23 g of an oxide of nitrogen nxoy, which occupies 120 cm3.
what are the values of x and y?
(assume 1 mol of gas molecules occupies 24.0 dm3.)
a x = 1, y = 1
b x = 1, y = 2
c x = 2, y = 1
d x = 2, y = 4
