The average fuel value of sugars is 17 kjmol a 2.0 l pitcher of sweetened kool-aid contains 400 g of sugar what is the fuel value in kj of a 500-ml serving of kool-aid?

what...who the hell would know that i do know that you can have black and blue hair and it is AWESOME

fuel value of sugar is 17kj/g. you have a 2L pitcher of kol-aid that contains 400g of sugar. fuel value of 500ml.

17kj/g * 400g = 6800Kj

there is 2000ml in 2L

so divide 6800 by 4 = 1700 or 1.7 x 10^3
