"How many moles of carbon dioxide are there in a 50.0 dm3 sample of the gas at a pressure of 100.0 kPa and a temperature of 50 degrees celsius?" 1.86 moles
The volume is 128,8 L.
1.86 moles
2.0 moles
25 deg. Celsius is about "room temperature," and assuming normal pressure (1atm) carbon dioxide is a gas.
The same as most substances, CO2 must be cooled and put under increased pressure to become a solid. At one atmosphere, CO2 must be cooled to a temperature of -78.5 degrees Celsius to solidify. At height pressures CO2 solidifies at higher temperatures, however solid CO2 never exists at a temperature above -56.4 degrees Celsius.
It is 31 Celsius.
The pressure is 39,8 torr.
The triple point of Carbon Dioxide is 216.58 K (-56.57 °C), 518.5 kPa (5.117197 atm) so pushing the pressure higher and the temperature lower shifts it solidly into the solid phase. Another way of checking it is to note that the vapor pressure of solid Carbon Dioxide at -60 °C is 4.043 atm so increasing the pressure to 15 atm would certainly push it further into the solid phase.

At standard pressure, CO2 does not occur as a liquid, the solid phase turns directly into a gas. Liquid carbon dioxide only forms at pressures higher than 5.1 atm. The actual boiling point depends on the pressure. At a particular pressure the liquid may have any temperature between the melting and boiling points. At the lowest pressure where it can exist, liquid carbon dioxide would have a temperature of -56.6 degrees C, or -69.88 degrees F. Under normal pressure conditions, carbon dioxide goes from gas straight to solid when the temperature reaches - 78.5 degrees C.
CO2, or carbon dioxide, will freeze at -78 degrees Celsius at normal pressure.

At higher temperatue it decomposes and the carbon content can get converted to carbon dioxide.
It is 31 Celsius.
Henry's law constant for Carbon Dioxide at 20 degrees Celsius is: 1,6*10^3 ATM
Gasses that are in the air include nitrogen, oxygen, carbon dioxide and water vapour. Room temperature depends on where you are in the world. In the UK, the average room temperature is 22 degrees Celsius, which is 72 degrees Fahrenheit.
