Question

The combustion of Ibuprofen C13H18O2 produces water and carbon

dioxide, I 100.0 g of Ibuprofen is combusted, how much carbon

dioxide is produced?

Answer 1

277.7 g of CO2

Step-by-step explanation:

Equation of reaction

C13H18O2 + 11O2 ---> 13CO2 + 9H2O

From the equation of reaction

1 mole of ibuprofen produces 13 moles of CO2

Molar mass of ibuprofen is 206g

Molar mass of CO2 is 44g

13 moles of CO2 weighs 572g

Therefore, 100g of ibuprofen will produce (100×572)/206 of CO2

= 277.7g
