Carbon dioxide lasers are used as cutting tools in industry medicine and research instruments and science in scientific laboratories to function such losers require a gas mixture is one mixture such as 1.24% carbon dioxide 97.2% helium and 1.56% nitrogen percents given here are more percent it’s a pressure of helium in the mixture is 88.5 ATM what is the pressure of carbon dioxide one ATM equals 14.7 psi equals 101.33K PA

A sample of carbon dioxide gas at a pressure of 0.556 atm and temperature of 21.2 oC occupies a volume of 12.9 L. If the gas is allowed to expand at constant temperature to a volume of 22.3 L, what will be the pressure of the gas sample in atm?   0.322 atm   0.644 atm   0.961 atm   0.529 atm

A gaseous mixture contains 12.4 g of N2 and 12.4 g of 02 that exerts a total pressure of 1.23 atm. What will the be the partial pressure of N2 in the mixture? 0.615 atm O 0.656 atm O 0.375 atm O 0.885 atm

A sample of helium gas has a volume of 1.20 L. More helium is added with no change in temperature or pressure until the final volume is 6.00 L. By what factor did the number of moles of helium change?     increase to 4 times the original number of moles       decrease to ¼ of the original number of moles       increase to 6 times the original number of moles     increase to 5 times the original number of moles     decrease to ⅕ of the original number of moles

A balloon filled with a certain gas has a volume of 1.0 L and a pressure of 1 atm, what is the volume when the pressure is decreased to 0.80 atm? A sample of carbon dioxide gas has a volume of 5.0 mL at a temperature of 22.0 °C. What is the final volume of the sample when the temperature is 0.0°C?

COMBINED GAS LAW A gas has the initial conditions of: 21.2 Liters 279 K 1.03 atmospheres If its temperature is increased to 411K and its pressure reduced to 0.28 atmospheres, what w volume be?
