the number of moles of oxygen in 1 litre of air containing 21% oxygen by volume in standard conditions is
Answered by admin @
At standard conditions, 1 liter of air at 21% oxygen possesses 0.21 L of oxygen. Since at STP 1 mole of gas occupies 22.4 L, simply divide 0.21/22.4, to arrive at0.0094 moles of oxygen.
