1. What is the density (in g/L) of O2 gas at 6.2 atm and 56.1 degrees C? Calculate answer to one decimal place regardless of sig figs. 2. A mixture of 7.3 moles of N2 and 4.3 moles of H2 are placed into a 11.9 L container at 298 K. What is the partial pressure of N2 (in atm)? Report answer to one decimal place regardless of sig figs. 3. A mix of 2.7 moles of He and 4.8 moles of Ne are placed into a 3.0L container at 8.0 degrees C. What is the total pressure in the container (in atm)? Report answers to one decimal place regardless of sig figs.

1. What is the density (in g/L) of O2 at 88.7Ā°C and 389.4 mmHg? Enter to 3 decimal places. 2. 125 mL of hydrogen gas, measured at 23Ā°C and 1.3 atm pressure, and 214 mL of nitrogen gas, measured at 23Ā°C and 2.3 atm pressure, were forced into the 125 mL container at 23Ā°C. What would be the pressure of the mixture of gases now in the 125 mL container? Enter to 2 decimal places.

2-a: If the pressure acting on an ideal gas at constant temperature is tripled, its volume is A) reduced to one-third. B) increased by a factor of three. C) increased by a factor of two. D) reduced to one-half. E) unchanged. 2-b: A balloon originally has a volume 1.0-mĀ³ when the gas in it is at 20Ā°C and a pressure of 1.0-atm. As it rises in earthā€™s atmosphere, it reaches a height where the temperature is -40Ā°C and pressure is 0.1-atm. What will be its new volume?

00:01 In the first question, the initial pressure p1 is given which is 5 multiplied by 10 to 5 pascal and the volume is given v1 which is 2 meter cube.
00:18 Now the final pressure is given 1 atmosphere so converting into pascal which will be 1 .01 multiply by 10 -nish to 5 pascal we have to find the volume v2 so here we can write this as according to the boil slow when the temperature is remained constant p1 v1 can be written as equal to p2 v2 we have to find the value of v2 so this will be p1 v1 divided by p2 this will be 5 multiply by 10 to 5 pascal v1 will be 2 it will be 1 .01 multiply by 10 days to 5 this will be cancelled out so here we will get the volume of the gas will be 9 .9 meter cube this will be the answer of question 1 now in the question 2, the volume v1 is given 1 meter cube, then the temperature is given, 27 degrees celsius converting into kelvin, this will be 300 kelvin, and the pressure p1 is given, 1 atmosphere...
