Answer to Question #123209 in General Chemistry for Nini

Question

C3H8 + 5 O2 - - - - - - - - > 3 CO2 + 4 H2O
Calculate how many molecules of CO2 are produced when 2.3 x 10^6 atoms of O2 are reacted.

Answer 1

C3H8 + 5O2 ..................3CO2 + 4 H2 O

Mole ratio 1 : 5 : 3 : 4

5 O2 ........... 3 CO2

5 : 3

[( 2.3)(10)6 (3)] / (5)

(6900000)/(5)

1380000 = 1.38 (10)6
