The data:

The calculation:

How much heat was absorbed by the water?
- Equation: q = (mass of water)(T_f-T_i)(1.00 cal/g-^oC)
  - (a) (53.33 g of H₂O)(45.3 ^oC - 15.9 ^oC)(1.00 cal/g-^oC)
    = 1570 cal. or 1.57 Cal;
  - (b) (67.65 g of H₂O)(37.8 ^oC - 15.8 ^oC)(1.00 cal/g-^oC)
    = 149 cal or 1.49 Cal;
  - (c) (53.33 g of H₂O)(66.5 ^oC - 27.8 ^oC)(1.00 cal/g-^oC)
    = 2062.71 cal or 2.06 Cal;
  - (d) (67.65 g of H₂O)(51.7 ^oC - 36.1^oC)(1.00 cal/g-^oC)
    = 1055.34 or 1.06 Cal.
Calories per gram of Cheetos (for a, b, and d)
- (1.57 Cal)/(1.13 g) = 1.39 Cal/g
- (1.49 Cal)/(1.12 g) = 1.33 Cal/g
- (1.06 Cal)/(0.83 g) = 1.28 Cal/g
  - Average 1.33 Cal/g
Mass of Cheeto in experiment (c) = q/1.33 Cal/g
- (2.06 Cal)(1.33 Cal/g) = 1.54 g
