P= pressure
V=volume
n=# of moles
R=gas constant
T=temperature

The ideal gas law equation (PV=nRT) uses Pressure (P), Volume (V), number of moles (n), a universal gas constant (R), and Temperature (T)

P is pressure
V is volume
n is number of moles
R is the ideal gas constant
T is temp
In this unit, remember that n/v is molarity and can allow us to calculate concentration when given pressure.

Remember that this equation can be rewritten as P=nRT/V, and n/V is the same as concentration. So, P=concentration times RT.

P: Pressure
V: Volume in liters
n: number of moles
R: Ideal gas constant
T: Temperature in Kelvin

P is pressure, v is volume, n is the number of moles, R is the Ideal Gas Constant (8.314 J / mol·K), and T is the temperature in K.

Knowing these comes in handy when given their values and you have to rearrange them in order to find a solutions concentration, for example. Notably, concentration (or n/V) = P/RT.

Pressure x Volume = Moles x Ideal Gas Constant x Temperature (in kelvin)

P- Pressure
V- Volume
n- Amount in moles
R- The ideal gas constant (depends on the units you are using)
T- Temperature

P and V are inversely related. Assuming a constant temperature, when pressure increases volume decreases and so forth.
