The weight of 11.2 liters of CO2 at STP would be

Explanation

Here's how to solve the problem:STP conditions:Standard Temperature and Pressure (STP) define a temperature of 0°C (273.15 K) and a pressure of 1 atmosphere (101.325 kPa).Molar mass of CO2:The molar mass of CO2 is approximately 44 g/mol, meaning 44 grams of CO2 contain 1 mole of CO2 molecules.Volume and moles:We are given the volume of CO2 at STP: 11.2 liters.Under STP conditions, 1 mole of any ideal gas occupies a volume of 22.4 liters.Therefore, 11.2 liters of CO2 represent:Volume / Volume per mole at STP = 11.2 L / 22.4 L/mol ≈ 0.5 mol of CO2Mass of CO2:Knowing the number of moles and the molar mass, we can calculate the mass of CO2:Mass = Number of moles * Molar massMass = 0.5 mol * 44 g/mol ≈ 22 gramsTherefore, the weight of 11.2 liters of CO2 at STP is 22 grams.
