a tank contains helium gas at 490 mmHg, nitrogen gas at 0.75 atm, and neon at 520 torr. What is the total pressure in atm?

Dalton's Law says that the total pressure of a system is the sum of the individual partial pressures of any gas(es) present.
If you convert torr and mmHg to atm ( by dividing them by 760) and add all the atm together you get 2.07
