help Please answer these questions on your Page 11(a)In a 20.0 L steel container, we have only 88.8 g of CO₂(g), 66.6 g of N₂(g), and 99.9 g ofan unknown gas. The temperature is 25.0°C and the total pressure is 7.77 atm. What is the molarmass of the unknown gas? The molar masses of C, N, and O are 12.01, 14.01, and 16.00 g/mol.(b)HA is a weak acid. We mix 2.000 L of a 0.555 M solution of HA with 1.000 L of a 0.333 Msolution of NaOH. The pH of the solution produced (with a total volume of 3.000 L) is 3.88. Whatis the value of the dissociation constant, K₁, for this weak acid HA? The temperature is 25.0°C.
