6. A breathing mixture is prepared in which He is substituted if N2. The gas is 79% He and 21% O2, by volume. (a) What is the density of this mixture in grams per litter at 25°C and 1 atm? (b) At 25°C, what pressure would the He-O2 mixture have the same density as that of air at 25°C and 1 atm? (air composition: 78.08% N2, 20.95%O2, 0.93% Ar, and 0.036% CO2 by volume)
