Calculate the number of moles of which contain 8.00 grams of .
When lead sulphide, PbS and lead oxide, PbO, are heated together the products are lead metal and sulphur dioxide, SO2.
PbS(s) + 2PbO(s) 3Pb (l) + SO2 (g).
If 14.0 g of lead oxide reacts according to the above equation, how many (a) moles of lead (b) grams of lead, (c) atoms of lead and (d) grams of sulphur dioxide are formed?
(Atomic mass : Pb = 207.0, S = 32.1 ; O =16.0)
