    how did you get 97, NH4NO3 is 80 g/mol

      Shlongton * it’s wrong ... what a silly mistake

    I'm guessing 4.184 J/gK was just given to us

      4.184 J/gK is the specific heat of water, that's always a known, I thought I should make that clear even though you made this comment a year ago which probably means you're not in chem anymore

    Why u don't use temperature in Kelvin (K) so that u can cancel out units
    It is necessary to use temp in degree Celsius whereas the specific heat is( J/gK)?

      The change in temperature (∆T) is the same in ºC and K, so you can skip the conversion to K. I hope this helps.

      change in kelvin is same as change in celsius

    How about calculating the molar mass of NH4NO3 correctly before making tutorial videos
