Does anyone know how to do this

Propane burns completely in oxygen according to the equation:
C3H8(g) + 5O2(g) → 3CO2(g) + 4H2O(g)
The amount of energy released per tonne of
carbon dioxide produced is determined to be
1.68 × 104 MJ t–1.
Determine the ΔH value, in kJ mol–1, for the thermochemical equation. (1 tonne = 106 g)

thank youuu

Ohh ok but how do we whether to work out it’s dilation from the X or Y axis if it doesn’t say in the question?

How do we know whether the question wants us to give the dilation from x axis or y axis when given both the original and transformed function.

For example:
f(x)= 1/x²
f1(x)= 5/x²

I got dilation by a factor of 1/5 from the y axis but the answers say factor of 5 from the x axis. Is my answer still valid?
