Aserving fish contains 50 g of protein and 4 gof fat. if protein has a caloric calue of 4.0 kcal/g and fat has 9.1 kcal/g, how many kcal are in the serving?

there are 236.4 kcal in the serving fish

Explanation:

1 g of protein has 4.0 kcal thus 50 g will have 50 x 4.0 = 200 kcal

1 g of fat has 9.1 kcal thus 4 g will have 4 x 9.1 = 36.4 kcal

the total kcal present in the serving will be the sum of kcal from protein and fat

200 kcal + 36.4 kcal = 236.4 kcal
