Answer:
1.977 grams
At one atmosphere and 0 degrees C, the density of CO2 gas is 1.977 grams per liter. Multiply the volume, in liters, by 1.977 to get the number of grams of CO2.

Answer:
The answer to your question is T = 7.25 °K
Explanation:
Data
Temperature = ?
moles = 0.80
volume = 275 ml
pressure = 175 kPa
constant of ideal gases = 0.082 atm l/ mol °K
Process
1.- Use the ideal gas law to solve this problem
PV = nRT
-Solve for Temperature
T = PV / nR
2.- Convert Pressure to atm
1 atm --------------- 101.325 kPa
x --------------- 175 kPa
x = (175 x 1) / 101.325
x = 1.73 atm
3.- Convert volume to liters
1000 ml ---------------- 1 l
275 ml ----------------- x
x = (275 x 1) / 1000
x = 0.275 l
4.- Find the temperature
T = (0.275 x 1.73) / (0.8 x 0.082)
-Simplification
T = 0.476 / 0.0656
-Result
T = 7.25 °K
Explanation:
The absolute temperature is the lowest possible temperature in the universe. At this temperature, all atoms become motionless and cease to move.
The value of the absolute zero is pegged at -273.16°C.
- It is the lowest limit of the coldness of a body.
- Nothing can be colder than a body at absolute temperature.
- Many researches are underway to take advantage of this temperature value for scientific purpose.
- Thermodynamically, all process stops at this temperature.
- When a body is brought close a body at absolute zero, it can suffer cryogenic burn due to heat transfer.
Yes, they do. The process described is a chemical reaction and it implies the change of nature of reactants and, of course, the change of its properties.
