    Hi does anyone know what happens to Q(energy transferred) and the value of delta H if the relative formula mass of the fuel burnt was inaccurately recorded e.g. used 50 instead of 60 in n=m/Mr and also what effect would there be on delta H if the fuel was heated for a longer duration?

    Thanks!
