## The Ideal Gas Equation Edit

Formula is **pV = nRT**

- p is
**pressure**in**Pa**(Pascals) - V is
**volume**in**m**(metres-cubed)^{3} - n is
**moles**(no units) - R is the
**gas constant**which is 8.31JK^{-1 }mol^{-1}(Note: You do not need to remember this as it will be give to you in the exam) - T is
**temperature**in**K**(Kelvin)

### How to work out Edit

- 1 atm is 100,000 Pa or 101,000 Pa
- 100 kPa is 100,000 Pa

- From degrees Celsius°
**C**to**K**add+273 to the value - m
^{3 }to dm^{3}multiply by 1,000 - m
^{3 }to cm^{3 }multiply by 1,000,000 - Standard conditions is 100,000 Pa and 298K
