Please /sci/ help a freshman chemfag out, this ain't even homework, I'm just preparing for a test.

A 2g sample containing Cu and Mg is treated with a HCl aqueous solution. 7.48*10^(-3) mol of hidrogen H2 are produced. What's the percentage of Mg and Cu in the sample?

It makes me feel a lot of things.

>Or anything with a secret/top secret security clearance. People seem to not know about this one.

Yeah, but getting a clearance can take fuck long time, especially when you are getting approved for something like sponsorship.

Although the fact it can let you enter with a starting salary of 70k+ is pretty nice.

I dunno man but I know that feel. The few girls I have had interaction with, all I could suggest is that once you manage to start a converation, ask about her, whenever say asks you about something dont forget to keep going with 'well what about you' and stuff.
