WebApr 4, 2024 · But density is m/V, so flip the equation over to get: m/V = (MMP)/ (RT) = density of the gas. Now we need to insert the values we know. MM of oxygen gas or O 2 is 16+16 = 32 grams/mole P = 5 atm T = 27 °C, but we need absolute temperature. T K = T C + 273 T = 27 + 273 = 300 K m/V = (32 g/mol · 5 atm)/ (0.0821 L·atm/mol·K · 300 K) WebNov 2, 2024 · What temperature is helium at room temperature?
