Q 7ai)
i actually got this question for my mocks
here's the working
volume of oxygen left
according to question according to equation
1 mol 6.5 mol
if 20cm3 x??
so 20 x 6.5 = 130cm3
150-130 = 20cm3
so volume of oxygen left =
20cm3volume of carbondioxide formed
1 4
20 x??
so 20 x 4 = 80
volume of carbondioxide formed =
80cm3
