Respuesta :

Answer:

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
