the gas pressure in an oxygen tank is 3.90 atm at a temperature of 298 K .If the pressure decreases at 3.20 what is the temperature of the gas in kelvin

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
