the heat of combustion of ethane, c2h6, is 1560 kj/mol. what is the heat of combustion of ethane, in kj per gram?

52 kj/gm

Explanation:

the heat of combustion of ethane, c2h6, is 1560 kj/mol. what is the heat of combustion of ethane, in kj per gram?

ethane is C2H6 and has a molecular mass of (2X12) + (6X1) = 30m

1 mole of ethane = 30 gmsso

1560 kj/moe = 1560 kj/30gm =

52 kj/gm
