A Snickers bar contains 27.0 g of sugars, 4.0 g of protein and 12.0 g of fat. How many food calories (Cal) are contained in the bar? Assume that metabolizing 1 g of protein releases the same amount of energy as 1 g of carbohydrates.

232 kcal

Explanation:

Data provided in the question:

Contents of the snickers bar

27.0 g of sugars

4.0 g of protein

12.0 g of fat

Now,

we know

1 gram of sugars = 4 kcal

1 gram of proteins = 1 gram of carb. = 4 kcal

1 g of fat = 9 kcal

Therefore,

Total calories of snickers bar = (27 * 4) + (4 * 4) + (12 * 9)

= 108 + 16 + 108

= 232 kcal
