A sample contianing 7.83g of solid CO2 is put in an empty sealed 6.2L container at a temperature of 251.3K. When all the solid CO2 becomes gas, what will be the pressure in the container?

Calculate and report the density, in kg m-³, of air at 1.00 atm and 10.0 °C. Take the composition of air to be 79 mol% nitrogen and 21.0 mol% oxygen. The molecular weights of nitrogen and oxygen may be taken as 28.0 g mol-¹ and 32.0 g mol-¹ respectively. State any assumptions.

At a certain temperature and pressure, a 1.00 mol sample of argon gas is pumped into a 22.4 L rigid box that already contains 1.00 mol of nitrogen gas.  We would expect the argon gas to: Group of answer choices decrease the total gas pressure in the box by a factor of 2 occupy the entire 22.4 L volume of the box. increase the total gas pressure in the box by a factor of less than 2. spread out into the box, but the actual volume occupied but he gas cannot be known without pressure information. occupy only 11.2 L of the box.

9.12 A 50 wt% Ni-50 wt% Cu alloy is slowly cooled from 1400°C (2550 F) to 1200°C (2190 F). (a) At what temperature does the first solid phase form? (b) What is the composition of this solid phase? (c) At what temperature does the liquid solidify? (d) What is the composition of this last remaining liquid phase?

What are the relative humidity and dew point temperature of 1 kilogram of 25 degree Celsius air that contains 10 grams of water vapor?

How many pound moles of air are needed to completely burn 6.5 pound moles of Benzene
