1) On hot days, you may have noticed that potato chip bags seem to inflate even thougt they have not been opened. if i have a 250 mL bag at a temperature of 19 C and i leave it in my car that has a temperature of 60 C, what will the new volume of the bag be? assume constant pressure and number moles
2) if i have 2.4 moles of gas held at a temperature of 97 C and in a container with volume of 45 liters, what is the pressure of the gas?
If it takes 50.0 mL of 0.0250 M K2Cr2O7 to titrate 30.0 mL of a solution containing Fe2+, what is the molar concentration of Fe2+?
