How to solve the combined gas law formula?

Answer 1

Jeremiah Adams

For a given molar quantity of gas: #(P_1V_1)/T_1=(P_2V_2)/T_2#

In fact, we can change this equation to include the mole count:

#(P_1V_1)/(n_1T_1)=(P_2V_2)/(n_2T_2)# which of course is a form of the Ideal Gas Equation.

To solve the combined gas law formula, you rearrange the equation to isolate the variable you're solving for and then plug in the known values. The combined gas law formula is:

( P_1 \times V_1 / T_1 = P_2 \times V_2 / T_2 )

Where:

( P_1 ) and ( P_2 ) are the initial and final pressures,
( V_1 ) and ( V_2 ) are the initial and final volumes,
( T_1 ) and ( T_2 ) are the initial and final temperatures.

You can rearrange this formula to solve for any one of the variables. For example, to solve for ( P_2 ), you would rearrange the formula as:

( P_2 = P_1 \times V_1 \times T_2 / (V_2 \times T_1) )

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
