The Mole and Avogadro
WebFeb 20, 2024 · All the molecules are diatomic So, Equivalent weight = Molecular weight 2 Equivalent weight of H 2 = 2 2 = 1 Equivalent weight of O 2 = 32 2 = 16 Equivalent weight of Cl 2 = 35. 5 2 = 17. 25 Now, at STP equivalent volume of gas is 22. 4 L 2 g of H 2 has equivalent volume 22. 4 L So, 1 g of H 2 has equiavelnt volume 22. 4 2 = 11. 2 L 32 g … WebVolume, gal = 0.785 x (0.69 ft 2) x 1800 ft x 7.48 gal/ft 3 (which equals 0.0073 MG) ... If your measurement is given in lbs, but you need kg, the conversion to use is (1 lb/0.453 kg). Sometimes everything is given in either pounds or kilograms and no conversion is needed. Either way you are determining the percent strength. WebThe molar volume of a gas expresses the volume occupied by 1 mole of that respective gas under certain temperature and pressure conditions.. The most common example is the molar volume of a gas at STP (Standard Temperature and Pressure), which is equal to 22.4 L for 1 mole of any ideal gas at a temperature equal to 273.15 K and a pressure equal to … bonus for using bing
