Gas constant for torr
WebMar 6, 2024 · Charles's law states that the volume (V) of a gas is directly proportional to the temperature (T) when pressure is kept constant.The temperature must be measured with the Kelvin scale.When we compare the substance under initial (V₁, T₁) and final conditions (V₂, T₂), you can write Charles' law as V₁/T₁ = V₂/T₂.As the temperature increases, the … WebPressure is in torr, volume is in liters, and temperature is in kelvin which means your value of the universal gas constant should have those same units. Which means you want to use 62.364 with units of L*torr*K^ (-)*mol^ (-). That was most likely your mistake, that you used the incorrect version of 'R'. Hope that helps. 2 comments ( 4 votes)
