Question

calculate the amount of water produced by 32g of methane

Answer 1

REQ EQ'N:

CH4 + 2O2 ----> CO2 + 2H2O

therefore one mole ch4 give 2 moles h20 therfore 2 moles ch4(since one mole wt 16g) give 4 moles h2o i.e 4*18g of h20 which is 72g of h2o

Answer 2

32 g of .ethane produces 72 g of h20
