This problem is providing information about the initial mass of mercury (II) oxide (10.00 g) which is able to produce liquid mercury (8.00 g) and gaseous oxygen and asks for the resulting mass of the latter, which turns out to be 0.65 g after doing the corresponding calculations.
Initially, it is given a mass of 10.00 g of the oxide and 1.35 g are left which means that the following mass is consumed:
Now, since 8.00 grams of liquid mercury are collected, it is possible to calculate the grams of oxygen that were produced, by considering the law of conservation of mass, which states that the mass of the products equal that of the reactants as it is nor destroyed nor created. In such a way, the mass of oxygen turns out to be:

The total pressure of the gaseous mixture has been 5.37 atm. Thus, option D is correct.
The partial pressure has been defined as the pressure exerted by each gas in the mixture.
According to the Dalton's law of partial pressure, the total pressure of gas has been the sum of the partial pressure of the gases in the mixture.
The given partial pressure of gases in the mixture has been:
- Partial pressure of Nitrogen,
- Partial pressure of Oxygen,
- Partial pressure of Argon,
- Partial pressure of Helium,
- Partial pressure of Hydrogen,
The total pressure of the gaseous mixture has been:
The total pressure of the gaseous mixture has been 5.37 atm. Thus, option D is correct.
