What is the total pressure in atmof a mixture of three gases with partial pressures of 11.5kPa, 30.6 kPa and 12.2 kPa?

The net force is 100

Those are different gas lawshere is a brief description of themcharles's law states that volume and temperature are directly proportional to each other as long as pressure is held constant.  boyle's law asserts that pressure and volume are inversely proportional to each other at fixed temperature.gay-lussac's law introduces a direct proportionality between temperature and pressure as long as it is at a constant volume.    source:
