Answer to Question #251790 in General Chemistry for niki

Question

1. Calculate the volume in liters of CO 2 at STP, which could be produced from 7.25 g C 2 H 6.
2. Calculate the volume of O 2 at 100 o C and 1.25 atm, which would react with 7.52g of C 2 H 6

Answer 1

C2H6(g)+ O2(g) → CO2(g) +3H2O

Molar mass of C2H6 = 30.07

Molar mass of CO2= 44.01 

7.25/30.07= 0.241mol

Mole ratio = 1:1

0.241× 22.4= 5.4L
