Question

If a propane heater burns 38.95 g C3H8, it consumes

Answer 1

0.8830

and How many moles of oxygen are required to produce 37.15 g CO2? is 1.407

and What mass of propane is necessary to react with the amount of oxygen calculated in the previous question? is 12.41

Answer 2

The correct answer option is 0.883 moles
`C _ 3 H _ 8`

Step-by-step explanation:

We are to find the number of moles that are consumed when a propane heater burns 38.95 g
`C _ 3 H _ 8`.

For this, we will divide the mass (38.95 g) of propane (
`C _ 3 H _ 8`) by the molar mass which is:

C = 12.01

H = 1.01

`C _ 3 H _ 8 = 3 * 12.01 + 8 * 1.01 = 44.11`

Dividing the mass by 44.11 to get the number of moles consumed:

`(38.95)/(44.11)` = 0.883 moles
`C _ 3 H _ 8`
