I don't understand how to find the volume in this problem..

A flask containing 63.2 mL of neon gas was collected over water at 21C and 788 mm Hg. What is this volume of gas at STP? (WVP at 21C = 18.6 mm Hg)

    $\begingroup$ Hint: what do you know about the partial pressures of the gases? What is contributing to the 788 mmHg? $\endgroup$

    $\begingroup$ If you edit the question to reflect your initial efforts, you can flag it to be reopened. As of now, you have just copied your homework problem in as a question. More ideal would be if you could pinpoint the areas that are troubling you and ask a more conceptual question. $\endgroup$

    $\begingroup$ This question serves as a bad example for the homework policy. $\endgroup$ Feb 23, 2016 at 8:44
