@adi - dude see,
232g of WO3 reacts with 36g of C rite?
so 116g with 18g of C
y do u find the answer weird, ?? check the ratio
232-36
116-18
looks quite clear to me..

1)why 36g of carbon???
2)m not saying the ratio is wrong, wht i am confued about is the fact that less reducing agent is required to reduce a large amount of the substance...
i mean how can only 18g of carbon be used to reduce 116gg of WO3
my question is more practical based than theoretical.

oye dude!!
it must be 36 cause 12 is atomic mass and we using 3 moles so 3*12=36!
@d!_†oX!©:
ohhohhh...okk..got the first ans...Thanks vaan...bt my second one??
Ghost Of Highbury:
vaan?..where is vaan's answer??
oye dude
WO3's mol. mass - 232
3C's mol. mass - 12*3 = 36
so 232g with 36g
116 -> 18g
simple.
