Use the following equation:

C4H100 + 6 O2 - 4CO2 + 5H20

How many moles of O2 are needed to make 36.7 mol of CO2?

How are a mole and a dozen similar? Each represents a certain mass of material. Each names a given number of objects. Each identifies a specific volume. Each measures a given number of amus.

Four balloons, each with a mass of 10.0 g, are inflated to a volume of 20.0 L, each with a different gas: helium, neon, carbon monoxide, or nitrogen monoxide. If the temperature is 25.0°C and the atmospheric pressure is1.
