<p>A 250ml sample of gas at 25 degrees celcius and 755 torr will have what volume at STP?</p>
<p>250ml x 755 torr/760 torr x 273k/ 298k = 228 ml</p>
<p>If 755 torr is on top, then why isn't 298k, since they're both standard?</p>
<p>(p1v1)/t1=(p2v2)/t2
V2=(p1v1t2)/(p2t1)
so the new temperature is on top while the new pressure is on the bottom</p>
