Answer
640 Kilocalories
Work Step by Step
To answer this question, first we must convert 3.2 L to mL and then divide the value (3 200 mL) by 100; after that multiply it by 5.0 g and multiply the final quantity in grams of carbohydrate by the respective value (Kcal/g ) given by the table 3.7
3.2 L $\times$ 1 000 mL= 3200 mL
$\frac{3 200 mL}{100 mL}$ = 32
32 mL $\times$ 5.0 g= 160 g
160 g $\times$ 4 = 640 Kcal
