Question

15 gram of carbon molar mass 12 gram per mole is burnt in excess oxygen according to the following balance equation C + O2 gives CO2 what is the theoretical yield of Co2 molar mass 44 gram mole in grams​

Answer 1

Answer:

55

Explanation:

molar ratio of carbon and oxygen in compound CO2 is 1:2

mass of 1 mole of C is 12gm

15 grams in moles is 15/12 = 5/4

no. of moles of O is 2× (5/4) = 10/4

mass of one mole of oxygen is 16gm, mass of 10/4 moles = 10/4 × 16 = 40

total yeild of CO2 in gms is 15 + 40 = 55
