Step 1
4 L. Since we have 20 L of each gas, we can calculate the number of moles of each gas. $$n = \frac{V}{22.4}$$ where n is the number of moles and V is the volume. Show more…

Why do $1 \mathrm{~mol} \mathrm{~N}_{2}$ and $1 \mathrm{~mol} \mathrm{O}_{2}$ both exert the same pressure if placed in the same 20 - $\mathrm{L}$ container? Is the mass of the gas sample the same in both cases? Explain why it is the same or different, and if it is different, predict which gas sample weighs more.
20 L of H2 gas at STP weigh about 1) 44.8 g 2) 12.2 g 3) 1.8 g 4) 20 g
