yes you are correct but make sure you re-arrange the formula FIRST and then put in the numbers. Start with this formula \[pV = nRT\] ask your self what are we looking for? Temperature. so we solve for T \[\frac{ pV }{ nR } = T\] \[\frac{ 5.4atm*120L }{ 4.0mol*0.082mol ^{-1} L,atm, K ^{-1}} = T, \in kelvins\]

@Gir_16 those are just units, all you would have to do is divide (5.4*120)/(4*0.82) the units are just to show you that they cancel out and you're left with Temperature. let me show you

@Gir_16 as you can see all the units cancel out and we're left with temperature that's what we must find

just remember to always solve for the variable you're looking for FIRST then put in the numbers.
