# Use the following equation to answer the questions-Use significant fig.docx

Use the following equation to answer the questions.Â Â Use significant figures where appropriate. SHOW ALL YOUR WORK STEP BY STEP NEATLY.
2C 4 H 10 + 13O 2 ---> 8CO 2 +10H 2 O
a. What is the molar ratio of C 4 H 10 :CO 2
b. What is the molar ratio of O 2 :H 2 O
Solution
a)
moles of C4H10 = 2
moles of CO2 = 8
molar ratio of C4H10 : CO2 = 2 / 8
= 1 / 4Â Â  or 1:4
b)
moles of O2 = 13
moles of H2O = 10
molar ratio of O2 : H2O = 13 / 10Â Â  (or) 13 :10 (or)
= 1.3
.
