I have a packet of homework so I think I may post other questions that I'm stuck on later this weekend. So thats a heads up. This packet deals with Gas Laws. 1. Given 100 ml of dry gas measured at 37° C and 760 mmHg, what would be its volume at 60°C? I used Charle's Law and ...

Got a question 3. Given 325 ml of saturated gas at 760 mmHg and 25°C, what would be its volume if dry at the same pressure and temperature? I got confused when I read 'if dry' Does that mean I have to subtract something out of 760mmHg? And would I used the combined gas law and...
