If the density of oxygen atSTP is 1,429 g/L the mass of 180 L is 257,22 g.
If the mole of oxygen (O2) is 15,999 g the number of moles is 16,077.
0.25 moles
8,4 liters of nitrous oxide at STP contain 2,65 moles.
16,8 L of Xe gas at STP is equivalent to 0,754 moles.
The answer is 0,2675 moles.

A cubic decimeter is a liter, so we're talking 50L of oxygen gas at STP. 1mol of any gas at STP occupies 22.4L of space, so 50/22.4 = about 2.2mol of oxygen.
The amount of oxygen is 0,067 moles.
0.25 moles
8,4 liters of nitrous oxide at STP contain 2,65 moles.
16,8 L of Xe gas at STP is equivalent to 0,754 moles.
No. of moles = mass/relitive molecular mass in this case = 10/16 = 0.625 so that's 0.625 of a mole and a mole of anything contains 6.022 x 1023 atoms = 3.76 x 1023 atoms in 10g of oxygen.
The answer is 0,2675 moles.
The answer is 2,68 moles.
Approx 0.223 moles.
