Answer:
D. 0.36 g
Explanation:
When a gas is collected over water, the total pressure is the sum of the pressure of the gas and the pressure of the water vapor.
Ptotal = Pwater + PN₂
PN₂ = Ptotal - Pwater = 730 torr - 23.76 torr = 706 torr
We can find the mass of N₂ using the ideal gas equation.

CH₃COOH-CH₃COO⁻ is a conjugate acid-base pair. NH₃-NH₂⁻ is another conjugate acid-base pair
