Explanation / Answer

(13)

1000 cal = 1 kcal

then, 8034 cal = 1 * 8034 / 1000 = 8.034 kcal

(14)

1 g. protein = 4 kcal

then, 11 g. protein = 44 kcal

similarly, 1 g. fat = 9 kcal

then, 7 g. of fat = 63 kcal

therefore, total calories = 107 kcal

(15)

250 mg. = 5.0 mL

then, 0.500 *1000 mg. = 5.0 *0.500 * 1000 / 250 = 10 mL

(16)

density = mass / volume = 367 / 163 = 2.25 g/mL

(17)

q = m s * change intemperature

q = 13.4 * 0.108 * (42.1-25.6)

q = 23.9 cal/g.0C
