WebThe ideal gas law can be used to determine how many moles of air are contained in the flask: PV = nRT. where P is the gas's pressure, V is its volume, n is the number of moles, R is the gas's constant, and T is the gas's temperature in kelvins. The provided temperature must first be converted from Celsius to Kelvin: T = 1.1°C + 273.15 = 274.25 K. Web7 jun. 2024 · If I want to maintain a volume of air as 100 ml at pressure 1 atm and temperature 273 K , I should have 0.00353 mole of nitrogen molecules and 0.00094 … Web3 jan. 2024 · Convert the expressions above to obtain a molarity formula. As mass / volume = molarity * molar mass, then mass / (volume * molar mass) = molarity. Substitute the known values to calculate the molarity: molarity = 5 / (1.2 * 36.46) = 0.114 mol/l = 0.114 M. You can also use this molarity calculator to find the mass concentration or molar mass. popnchic eyelash
