4 C2H5O2N(s) + 9O2(g) ------------------- 8 CO2(g) + 10 H2O(l) + 2 N2(g)Â Â Î”HÂ°rxn=-3857 kj/mol

4 mole

molar mass of glycine= 75.07 g/mole

mass of one mole of glycine = 75.07 grams

mass of 4 moles of glycine = 4 x75.07 = 300.28 grams

according to equation

energy is transferred from 300.28 grams of glycine = 3857 Kj

enegy is transfereed from 17.00 grams of glycine = ?
