Question

The volume of a sample of oxygen is 200.0 mL when the pressure is 3.000 atm and the temperature is 37.0 oC. What is the new temperature if the volume increases to 400.0 mL and the pressure decreases to 2.000 atm?

Answer 1

Use PV = nRT. Remember to convert T to kelvin. The answer you want will come out in kelvin so remember to convert back to C if you want the anwer in degrees C. Also remember to convert mL to L. L is the unit for V. Post your work if you get stuck.
