If a propane heater burns 38.95 g c3h8, it consumes

The correct answer option is 0.883 moles

Explanation:

We are to find the number of moles that are consumed when a propane heater burns 38.95 g .

For this, we will divide the mass (38.95 g) of propane () by the molar mass which is:

C = 12.01

H = 1.01

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

= 0.883 moles

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

let that person have a turn to speak : )
