Weba 18-cm diameter cylinder that is 39 cm long containes 40g of oxygen gas at 20 degrees celcius. A) how many moles of oxygen are in the cylinder. answer: 1.3 molB) how many oxygen molecules are in the cylinder. answer: 7.5x10^23 moleculesC) what is the number density of the oxygen? answer: 7.6x10^25 m^-3D) what us the reading of a pressure. WebOxygen gas is the second most common component of the Earth's atmosphere, taking up 20.8% of its volume and 23.1% of its mass (some 10 15 tonnes). Earth is unusual among the planets of the Solar System in having such a high concentration of oxygen gas in its atmosphere: Mars (with 0.1% O 2 by volume) and Venus have much less. The O

WebApr 4, 2024 · So, start by converting the temperature of the gas to Kelvin by using T [K] = t[∘C] +273.15 −−−−−−−−−−−−−−−−−−−− You will have T = 166∘C + 273.15 = 439.15 K The volume of the gas will increase as temperature increases and decrease as temperature decreases. Mathematically, this can be written as V 1 T 1 = V 2 T 2 −−−−−−−−− Here Webthe temperature of 0°C and pressure of 1 atm. Avogadro's Law. equal volumes of all gases, at the same temperature and pressure, have the same number of molecules; the volume … WebThe calculator below can be used to estimate oxygen dynamic or kinematic viscosity at given temperatures and atmospheric pressure. The output dynamic viscosity is given as Pa*s, N*s/m 2, cP, mPa*s, lb f *s/ft 2 and lb m / (ft*h), while the kinematic viscosity is given as cSt, m 2 /s, and ft 2 /s Temperature Choose the actual unit of temperature: iturria arthur
