Wait, how does on mole of a gas occupy 22.4L

<p>If, according to the idea gas law, it should occupy 24.46L at STP?</p>

<p>PV=nRT
P=1, n=1
V=RT
V=.0821x298
=24.4658L</p>

<p>I don't get this...I did a 2007 Form B FRQ and it asked how much volume a sample of whatever fraction of a mole of H2 gas at STP would occupy, and you couldn't do it by multiplying the fraction of a mole by 22.4-you had to put it in the pv=nrt equation and get something different.</p>

<p>T = 273.15 K
edit: for some reason the K refuses to be capitalized
edit2: nvm</p>

<p>Oooooooh, wow. I feel dumb. I got my standard temperatures mixed (was reviewing electrochem before this ha).</p>

<p>Thanks.</p>
