What mass of oxygen is needed to fill a 585 L tank at STP?  Paired item 1)

Quizplus · Accepted Answer

At STP (Standard Temperature and Pressure), 1 mole of any gas occupies 22.4 L. The molar mass of oxygen (O2) is 32 g/mol. To find the mass of oxygen needed to fill a 585 L tank, first calculate the number of moles: 585 L / 22.4 L/mol = 26.116 moles. Then, multiply by the molar mass: 26.116 moles * 32 g/mol = 835.712 g, which is approximately 0.835 kg.
