Pressure and volume lab...very confused
I'm working with the calculations for a lab to measure pressure in a controlled environment.
The first table's text instructs: "Convert mL to L and 1/L and calculate."
The Data appears as follows:
Volume (mL) | Volume (L) | Calculate 1/V (L-1) | Pressure (mmHg) | Calculate P x V
20 mL | 0.020 (L) | This is the one I don't understand | 1141.1 (mmHg) | 22.822 (L/mmHg)
I believe that my final value (22.822 L/mmHg) will change if I knew how to calculate 1/V (L-1). I'm distracted by the negative exponent. From what I understand of Algebra, negative exponents have to be "flipttped" before any calculations can be performed. Furthermore, I haven't seen any gas Law formula written like this in our text book (Introduction To Chemistry - Karen C Timberlake).
If someone could clear this up so I can get on with the rest of my calculations I would be incredibly grateful.
