Ideal gas law formula: PV = nRT. P = Pressure. V = Volume. T = Temperature. n = number of moles of the substance. R = the ideal gas constant = 8.314 J/(mol·K) = 0.082 (L atm)/(mol K) ( R is equal to the Avogadro’s constant multiplied by the Boltzmann constant) Modifications to the ideal gas equation:

A fire extinguisher has a volume of 4.00 L and is filled with CO2 gas pressurized to -290 psi (19.7 atm) at 25°C. How many moles of CO2 are contained in the fire extinguisher? 38.4 mole 3.22 mole 9.25 mole 0.310 mole 17.6 mole
A 10B or higher rated fire extinguisher must be placed within 50 feet of an area where more than 5 gallons of combustible or explosive liquids, or more than 5 pounds of combustible gas, are being used.

How many fire extinguishers do I need for my home?
For a floor with an area exceeding 4300 square feet, the fire extinguishers should have a combined minimum fire rating of 0.065 x floor area (in square meters). In simple words, for every additional 2100 square feet, you must have an extra fire extinguisher. How Many Fire Extinguishers per Square Foot?
How do you calculate moles in ideal gas law?
The modified ideal gas law formula: Moles = (Pressure * Volume) / (0.0821 * Temperature) If you want to work it out yourself, without the molar mass of gas calculator, be careful with the units! This particular equation uses a constant of 0.0821, which is intended for the following units:
How high should a fire extinguisher be off the ground?
According to the NFPA, if a fire extinguisher weighs more than 40 lbs, the extinguisher’s top cannot be more than 3.5 ft. above the ground, and the bottom must be at least 4 inches from the ground.
How many particles are in a mole?
A mole is a unit used for measuring matter. One mol contains exactly 6.02214076×10²³ elementary particles (this number is called the Avogadro’s Number ). When we use g/mol, we describe the weight of one mole of a given substance.
