A patient receives 2500mL of an IV solution containing 2g of glucose per 100 mL.

**1. How much energy, in kilojoules, does the patient obtain from glucose, a carbohydrate?**

Express your answer to two significant figures and include the appropriate units.

Express your answer to two significant figures and include the appropriate units.

2500 mL (2g/100mL) = 50g

50g (4kcal/1g) = 200kcal

200 kcal (4.184J/1kcal) = 836.8J

836.8J (0.001kJ/1J) = 0.8368kJ rounded to 2 significant figures would be 0.84kJ correct?

**2. How much energy, in kilocalories, does the patient obtain from glucose?**

Express your answer to two significant figures and include the appropriate units.

Express your answer to two significant figures and include the appropriate units.

2500 mL (2g/100mL) = 50g

50g (4kcal/1g) = 200kcal rounded to 2 significant figures would be 2.0 x 102 correct?

Using the following data, determine the kilocalories for each food burned in a calorimeter.

**1. One cup of popcorn that changes the temperature of 1.20×103g water from 28.5∘C to 52.7∘C**

1.20 x 103g (4.184J / 1g x 1 degree C)(52.7 degrees - 28.5 degrees) = 121503.36J

121503.36J (1 kcal/ 4.184J) = 29040 kcal rounded to 3 significant figures would be 29.0 x 103 kcal correct?

**2. A sample of olive oil that increases the temperature of 417g water from 25.6∘C to 41.7∘C**

417g (4.184J / 1g x 1 degree C)(41.7 degrees - 25.6 degrees) = 28090.1208J

28090.1208J (1 kcal / 4.184J) = 6713.7 kcal rounded to 3 significant figures would be 6.71 x 103 kcal correct?
