What A Monday

Got tattled on right off the bat. It's happened before, this older lady has it out for me. Her riotous conservatism doesn't meld with my hippie liberalism. Oh well, I will work with her like I have been, with a smile and snarky comments.
Met with my advisor, can I do 16 credits? I don't know.

Check out this problem we did in Chemistry. I just wanted it to someday look back on:

A student carries out a reaction and collects a total of 154.4ml of H2 gas at a pressure of 742mmHg and a temperature of 25C. What mass, in mg, H2 did the student collect?

PH2=742mmHg - 23.78mmHg= 718mmHg
718mmHg(1atm/760mmHg) = 0.945atm
154.4ml(1L/1000mL) = 0.1544L
25+273 = 298K
(0.945atm)(0.1544L)/(0.0821)(298K) = 5.97x10^-3molH2
2(1.0008g) = 2.02 g/mol
5.97x10^-3mol(2.02g/1mol) = 0.0120g
0.0120g(1000mg/1g) = 12.0mg

Yeah, that's one problem.
Finished two tests today - done for the day. My head hurts and I'm exhausted.
