What volume does 16.0g of o2 occupy at stp
Hello, at STP a standard gas has 22.4 L volume and 1 atm pressure. The atomic mass of one mole of O2 gas would be 32 g. And this is 16 g of 02 which would mean that there is 16g/32g = 0.5 mol O2 gas. So, if 1 mol of any standard gas at STP is 22.4 L then 0.5 mol would be 11.2 Liters. Hope this helps.
