Problem 75P

Octane (C8H18) is a component of gasoline that burns according to the equation:

What mass of octane (in g) is required to produce 1.55  103 kJ of heat?

Step-by-Step Solution:
Step 1 of 3

Solution 75P

From the equation given above it is clear that 1 mole of C8H18 releases -5074KJ of energy

The amount of C8H18 that will release 1.55 × 103kJ of heat will be= -1.55 ×103kJ=0.30moles

Molecular mass of C8H18=8 ×12+18 ×1=114g

Weight in grams of  C8H18=Number of moles ×Molecular mass=0.30 ×114=34.2grams

Thus 34.2 grams of octane will release 1.55 × 103kJ of energy

Step 2 of 3

Step 3 of 3
