What volume does 0.25 moles of oxygen gas occupy at STP?
Web26 jun. 2016 · Our only unknown is the number of moles. Our known variables are P,V,R, and T. At STP, the temperature is 273K and the pressure is 1 atm. The proportionality constant, R, is equal to 0.0821 L × atm mol × K. Now we have to rearrange the equation to solve for n: n = P V RT. n = 1atm ×48.6L 0.0821 Lxxatm mol× K ×273K. n = 2.17mol. Web4 aug. 2024 · We start by determining the number of moles of gas present. We know that 22.4 liters of a gas at STP equals one mole, so: 867 L × 1 mol 22.4 L = 38.7 mol We also know the molecular weight of N 2 ( 28.0 g/mol), so we can then calculate the weight of nitrogen gas in 867 liters: 38.7 mol × 28 g 1 mol = 1083.6 g N 2 Step 3: Think about your … Web6 okt. 2024 · Being the molar mass of O₂, that is, the mass of one mole of the compound, 32 g/mole, the amount of mass that 1.97 moles contains can be calculated as: = 63.04 g ≈ … ironing hair in the 1960s
