Anna007 [38]

Calculate the food energy (joules/g) of one of your food samples. one chemistry calorie is equal to 4.186 joules. convert the energy you calculated to kilojoules (1 kj = 1000 j). since nothing is given, an example is avocadoes have 160 cal/100 g serving

(160 cal/ 100 g)(4.186 J/ 1 cal) (1 kJ/1000 J) = 0.0067 kJ/g

A large weather balloon filled with helium has a volume of 7.00 x 102 L at STP. Which expression should be used to find the mass
balandron [24]

Answer:

mass of Helium = mole of Helium x Molarmass of Helium

Explanation:

Mole of Helium = volume of Helium/ 22.4dm^3/mol

                          = 7.00 x 10^2/22.4

                          = 31.25mol

Mass of Helium = mole of Helium x Molarmass of Helium

                           = 31.25mol x 4g/mol

                           = 125g
