R bar chemistry
Webconstant! The ideal gas law is: pV = nRT , where n is the number of moles, and R is universal gas constant. The value of R depends on the units involved, but is usually stated with S.I. units as: R = 8.314 J/mol·K . For air, one mole is 28.97 g (=0.02897 kg), so we can do a unit conversion from moles to kilograms. = 8.314 ∙ × 1 0.02897 ˙ = WebSep 26, 2024 · HIGHLIGHTS Bar Admission: 2015 US Patent and Trademark Office (Registration # 73850) Senior Scientist, Chemistry A dynamic professional, registered before the US Patent and Trademark ...
