The vanadium in 50cm3 of a 0.8
WebMar 27, 2024 · What is the pressure of 0.1 moles of a gas at 50 °C in a cubic meter? 268.7 Pa, or 0.00265 atm. To find this result: Convert the temperature into kelvin: T [K] = 273.15 + 50 = 323.15 K. Compute the product of temperature, the number of moles, and the gas constant: nRT = 0.1 mol × 323.15 K × 8.3145 J·K/mol = 268.7 J (that is, energy ).
