Answer:

The total pressure will be 1, 021 atm

Explanation:

We apply Dalton's law, where for a gas mixture the total pressure is the sum of the partial pressures of each gas that makes up that mixture. The unit of pressure is converted into atm:

760mmHg----1 atm

542mmHg----x=(542mmHgx 1 atm)/760mmHg=0,713 atm

234mmHg----x=(234mmHgx 1 atm)/760mmHg=0,308 atm

Pt=P Ne + P At= 0,713 atm + 0,308 atm= 1, 021 atm
