### Why is the ideal gas law important?

The ideal gas law is an equation of state the describes the behavior of an ideal gas and also a real gas under conditions of ordinary temperature and low pressure. This is one of the most useful gas laws to know because it can be used to find pressure, volume, number of moles, or temperature of a gas.

### What is the formula for the ideal gas law?

The formula for the ideal gas law is: PV = nRT. P = pressure. V = volume. n = number of moles of gas. R = ideal or universal gas constant = 0.08 L atm / mol K. T = absolute temperature in Kelvin. Sometimes, you may use another version of the ideal gas law: PV = NkT.

### Do we need to use the ideal gas law twice?

We are being asked to change the conditions to a new amount of moles and pressure. So, it seems like the ideal gas law needs to be used twice. 2) Let’s set up two ideal gas law equations: P1V1= n1RT1

### How do you solve the gas constant problem in chemistry?

In order to solve the problem we need to start by checking to make sure our units are in order. To do this let’s look at the units of the ideal gas constant, which are liters (L) times atmospheres (atm) divided by Kelvins (K) times moles (mol).
