Dennis_Churaev [7]3 years ago
5 0

Answer: Định luật Raoult là một định luật hóa học vật lý, với ý nghĩa trong nhiệt động lực học. Được thành lập bởi nhà hóa học người Pháp François-Marie Raoult vào năm 1887, nó nói rằng áp suất một phần của mỗi thành phần của một hỗn hợp chất lỏng lý tưởng bằng với áp suất hơi của thành phần tinh khiết nhân với phần nốt ruồi của nó trong hỗn hợp. Kết quả là, việc giảm áp suất hơi tương đối của dung dịch pha loãng của chất tan không lây bằng với phần nốt ruồi của chất tan trong dung dịch.

calculate the volume od a CO2 cartridge that has a pressure of 850 PSI at a temperature of 21ºc the cartridge contains 0.273 mol
gladu [14]
Answer is: volume of CO₂ is 0,113 dm³.
Ideal gas law = pV = nRT.
p = 850 PSI = 5860543,6992 Pa.
Psi <span>is the abbreviation of pound per square inch.
T = 21</span>°C = 294,15 K.
n = 0,273 mol.
R = 8,314 J/K·mol.
V = nRT ÷ p
V = 0,273 mol · 8,314 J/K·mol · 294,15 K ÷ 5860543,6992 Pa.
V = 0,00011 m³ = 0,113 dm³.
