What are the units used in $PV{\\text{ = nRT}}$.. Ans: Hint: In physical chemistry this relation is very important as this relation is valid for ideal gases and thus termed as ideal gas law. We can calculate pressure, volume of a gas in a closed co...
PV=NRT和22.我很困惑一些题比如说if 3.20 grams of a gas(mol .wt.equal to 125) were collected over water at 22摄氏度 and at a barometric pressure of 756 mm of hg,what would be the volume of the gas.我觉得这道题就是用PV=NRT算...于是就是(3.2/125*0.0821*(22+273))/(756/760)...
