An ideal gas as well as any gas can be characterized by four variables and one constant. where: measured pressure. Avogadro's Law is in evidence whenever you blow up a balloon. Pump gas molecules to a box and see what happens as you change the volume, add or remove heat, and more. A container holds three gases: oxygen, carbon dioxide, and helium. reaction; Nh4HS (g)<==> NH3 (g) + H2S (g) step 1; some NH4HS decomposed in an evacuated container to give a total pressure at equililbrium of .659 atm. Avogadro's Law. Explanation: According to avogadro's law, 1 mole of every substance weighs equal to molecular mass and contains avogadro's number of particles.. To calculate the number of moles, we use the equation: moles of (1kg=1000g). 3) Methane and carbon dioxide react in a 1:1 volume ratio: 1 is to 1 as 2.00 L is to x x = 2.00 L of CO 2 produced at 298 K and 2.00 atm. Therefore, the volume of one mole of gas at STP= 8.314 J.mol -1.K-1273.15 K (101.325 k Pa)= 22.4 Litres. 65. In 1814 French Physicist Andre-Marie Ampere published similar results.
