The heat flow (calories) utilised to enable the heat of a concentration to be determined is fixed to a certain value in centigrade (° C) (1 kcal or 1000 cal). Electrostatic is a SI vital part (J) for energy production. 4.18 kJ is a substantial calorie intake.

The whole milk contains of $12g$of carbohydrate, $9g$of fat, and of$9g$ protein. Calculate the kilocalories for each type of food using the formula and round off to tens place.

Calculate the energy available from carbohydrates in kilocalories as follows:

kilocalories = mass $×$energy value

localid="1651904309634" $=(12g$of carbohydrate$)$localid="1651904317747" $\left(4\frac{kcal}{\mathrm{g}}\right)$

$=48kcal$carbohydrates

Calculate the energy available from fats in kilocalories as follows:

kilocalories = mass $×$energy value

localid="1651904342309" $=(9g$of fats$)$localid="1651904332983" $\left(9\frac{kcal}{\mathrm{g}}\right)$

$=81kcal$fats

Calculate the energy available from proteins in kilocalories as follows:

kilocalories = mass $×$energy value

localid="1651904364215" $=(9g$of protein$)$localid="1651904352186" $\left(4\frac{kcal}{\mathrm{g}}\right)$

$=36kcal$protein

Therefore, total energy in kilocalories is as follows:

$48kcal$carbohydrates $+81kcal$fats$+36kcal$ protein

$165kcal$
