Question

What weight of 80% pure sulphur is required to produce 64 gram of so2

Answer 1

Answer:

S + O2 ----------- -------------------------------------------------SO2

Now 1 mole of Oxygen gives one moles of sulphur dioxide.

5 S + 5 O2 ------------------------------------------------------------ 5 SO2

Hence it is clear from the equation that burning 5 moles of Oxygen will produce 5 moles of SO2.

Answer 2

S+O2 →SO2

64 kg SO2 requires 32 kg pure sulphur

We know that, 80 kg pure sulphur is present in 100 kg of sulpur sample

So 32 kg sulphur is present in

100×32

80

kg sample =40 kg
