if you burned a marshmallow with a net mass of 0.8g and you heated 49.1 g of water from an initial temperature of 24C to a final temperature of 28C what is the heat energy per gram of marshmallow? (express your answer in J/g)

a. 822 J/g
b. 1027 J/g
c. 4.184 J/g
d. 7210 J/g

  1. q = mass water x specific heat water x (Tinial-Tinitial).
    Then q/0.8 = J/g.
