Steve gave you the combined gas law, but it seems that you were confused. The gas law is as followed: P1V1/T1=P2V2/T2 Where P1=75.0 cmHg V1=500.0 mL T1=273K +(-185ºC)=88K P2=55.0 cmHg V2=221.0mL and T2=? Solve for T2: T2=[T1*(P2V2)]/P1V1 T2=[88K*(55.0 cmHg*221.0mL)/(75.0 cmHg*...

Chemistry- dilution
How many mols did you start with? That's M x L = 1.20 x 0.051 = 0.0612 and that is in 248 so the concn of the first solution is 0.0612/0.248 = about 0.25 but you should redo it for more accuracy. Then 124 mL of that is diluted. New concn is about 0.25 x [(124/(124+125)] = ?
