Propane (C3H3) is used in domestic cooking and heating. A typical home in Pennsylvania burns 750 gal of propane for heating over the course of a year. How many moles of propane are burned? (the density of propane is approximately 4.2lb/gal)

There are 32400 moles of propane burned.

Explanation:

To calculate the mass of propane, we use the equation:

Density of propane =

Volume of propane = 750 gal

Putting values in above equation, we get:

    (1 lb=453.6 g[/tex]

According to avogadro's law, 1 mole of every substance weighs equal to molecular mass and contains avogadro's number of particles.

To calculate the moles, we use the equation:

Thus there are 32400 moles of propane burned.
