Question

a serving of skippy superchunk peanut butter (32.00 g) contains 16.00 g of fat, 7.00 g of carbohydrate, and 7.00 g of protein. calculate the cal per serving. fat contains 9.00 cal/g, and carbohydrate and protein both contain 4.00 cal/g. the cal from fat is 1 cal the cal from carbohydrates is 2 cal the cal from protein is 3 cal the total cal is 4 cal a. 144 b. 200. c. 28.0 d. 64.0 e. 172 f. 56.0 g. 170

Explanation:

Step1: Calculate Cal from fat

Multiply fat mass by fat - Cal/g. $16.00\times9.00 = 144$

Step2: Calculate Cal from carbohydrates

Multiply carbohydrate mass by carbohydrate - Cal/g. $7.00\times4.00=28.0$

Step3: Calculate Cal from protein

Multiply protein mass by protein - Cal/g. $7.00\times4.00 = 28.0$

Step4: Calculate total Cal

Sum Cal from fat, carbohydrates and protein. $144 + 28.0+28.0=200$

Answer:

1. A. 144
2. C. 28.0
3. C. 28.0
4. B. 200.
