Ideal gas equation, PV = nRT , T propto (1/ n ) Where; n= number of moles =( text weight ( W )/ text molecular weight ( M )) ( T 1/ T 2)=( n 2/ n 1)=( W 2 M 1/ M 2 W 1)

Q. Which of the following expression is true regarding gas laws? $(W =$ weight, $M =$ molar mass $)$

$\frac{T _{1}}{T _{2}} = \frac{M _{1} W _{2}}{M _{2} W _{1}}$

$\frac{T _{1}}{T _{2}} = \frac{M _{2} W _{1}}{M _{1} W _{2}}$

$\frac{T _{1}}{T _{2}} = \frac{M _{1} W _{1}}{M _{2} W _{2}}$

$\frac{T _{2}}{T _{1}} = \frac{M _{1} W _{1}}{M _{2} W _{2}}$

Ideal gas equation,

$P V = n RT, T \propto \frac{1}{n}$

Where; $n =$ number of moles $= \frac{weight ( W )}{molecular weight ( M )}$

$\frac{T _{1}}{T _{2}} = \frac{n _{2}}{n _{1}} = \frac{W _{2} M _{1}}{M _{2} W _{1}}$

T2​T1​​=M2​W1​M1​W2​​

T2​T1​​=M1​W2​M2​W1​​

T2​T1​​=M2​W2​M1​W1​​

T1​T2​​=M2​W2​M1​W1​​
