<p>I have Gelbart's midterm in a few days, but I'm stuck on problem 3 on the practice midterm and problem 46 in the book, and none of my friends have any different ideas on how to solve it. </p>
<p>quantum</a> mechanics - probability of finding an electron</p>
<p>The link above states the exact problem as it appears in my textbook. If you have any suggestions/advice/solutions, I would appreciate it. Thank you in advance!</p>
<p>You'll get more help by posting it on something similar to an AoPs type forum than here I think...</p>
<p>you would've saved loads of time just asking someone to teach you integration. it's not like it's some really complex algorithm.</p>
<p>LOL my friend went to the TA's OH today, and he spent 30mins trying to solve it and couldn't do it... he told them he would get back to them tomorrow (tuesday). hes gonna try it on his own, and if he cant do it, hes gonna ask gelbart</p>
<p>yes... wednesday's midterm is gonna be fun... lol...</p>
<p>i don't think you need to integrate. you just plug in the appropriate r value into the wave function (since we're only working with s orbitals), square that value, and then multiple dV. as for part c of 46, there's a formula in the book and in his lecture notes for radial probability densities. you just have to plug in values for that part. good luck!</p>
<p>and if i wrote something wrong, someone please tell me.</p>
<p>what class is this for? 115A? I didnt know there were other physics majors on here. Maybe I've seen you guys before</p>
<p>okay, am I the only one here who feels COMPLETELY screwed for the midterm?? i am so lost it's not even funny and the midterm is tomorrow.</p>
<p>screw chem and gelbart's midterm
i used to like chem until i took this class...</p>
<p>The TA is a retard. This is just a plug and chug problem.</p>
<p>Probability = psi squared * Volume. Technically, probability is proportional to psi squared.</p>
<p>Doing part a as an example.
r = 0, therefore probability P = 22 x10^-10.</p>
<p>yea... i think the TA was dumb... he got it today, but was lost yesterday
yea dV is just the small volume, so you just need to multiply... no integration
thats how i was gonna do it anyway... its what made sense</p>
