Has anyone done the 2004 CSSA HSC Trial papers??
I was just wondering for question 23...
"Coal, containing 0.1% sulfur, is burned in a power station. Calculate the volume of sulfur dioxide released at 25 degrees Celsius and 100kPa when 10.0 million kg of coal is burned."
Supposedly, to work out the mass of sulphur... shouldn't it shud be 0.1% x 10^7??
Coz the answer booklet showed that the mass of sulphur is worked about as 0.01% x 1 x 10^10 = 1 x 10^6
Can someone plz tell me if i have done something wrong?
