Question

a) calculate the amount of carbon dioxide that could be produced when 1mole of Methanol is completely burnt (C=11, H=1, O=16)

b) How many moles of carbon atoms are present in three moles of ethane C2H6

Answer 1

a) 44g of CO2 is produced

b) 3 mole of ethane contains 6mole of carbon

____________________________________________________________________

a) 2CH3OH +3O2--->2CO2+4H2O

64g(2moles) of methanol-------> 88g(2moles)of CO2

32g(1mole)of methanol------->44g(1mole)of CO2

b) 3C2H6

C = 2 x 3 = 6

3mol of ethane contains 6mol of carbon
