Question

How many moles of C5H120 would it take to generate 4.2 moles of CO2 from combustion?

2 CsH120 + 15 O2 → 10 CO2 + 12 H2O

Answer 1

0.84 moles

Step-by-step explanation:

from the equation 2 moles of pentanol generated 10 moles of CO2 therefore, x mol of pentanol will generate 4.2mol of CO2.

making x the subject of formula=4.2*2/10

=0.84 moles of

pentanol
