A 3.00 L pitcher of sweetened ice tea contains 600. g of sugar. Assuming that the sugar is the only fuel source, what is the fuel value (in kJ) of a 250. mL serving? The respective fuel values for protein, fat, and carbohydrate are 17, 38, and 17 kJ/g, respectively.

Respuesta :

Answer:

Fuel value of 250 mL serving is 8.50 \times 10^2 kJ

Explanation:

Given data:

3.00 L contains 600 g of sugar

250 ml is 0.250 L

3 L consist of 600 g

1 L  consist 600/3

0.250 l consist [tex]600/3 \times 0.250 = 50 g[/tex] sugar

fuel value of carbohydrate is 17 kJ/g

50 g of sugar consist of fuel value of  = [tex]50 \times 17 = 850 kJ = 8.50 \times 10^2 kJ[/tex]
