79.4 grams of C3H8 are consumed with an excess of oxygen in the reaction 1 C3H8 + 5 O2 --> 3 CO2 + 4 H2O. How many moles of oxygen (O2), carbon dioxide (CO2), and water (H2O) are consumed in this reaction?

catya your not at all which answer i've seen you do this on another question!

answer: option (b) is the correct answer.

explanation:

intensive property is the physical property which does not depend on the size of system or amount of material present in system.

for example, color, density, melting point, boiling point etc are all intensive properties.

thus, we can conclude that the boiling point and color of a substance are both examples of intensive properties because they do not depend on the amount of matter in the sample.
