Found 8 sentences matching phrase "molar volume".Found in 8 ms. Sentence Examples. 5. The modified Rouse theory for unentangled melts also predicts that the longest relaxation time is proportional to the square of the molar … Usually to find an ELEMENT's molar mass, you look at your periodic table and look for that element's atomic mass (which will equal the molar mass) But because Oxygen is a diatomic element (O2), then you have to do 15.999 x 2 = 31.998 or just 16 x 2 = 32. of a gas? The simplicity of this relationship is a big reason why we typically treat gases as ideal, unless there is a good reason to do otherwise. 4.
