Question 1
acetone (ch3)2co is a volatile liquid that can be readily converted to vapour.
calculate the density of acetone vapour at 100,000 pa and 398 k in kg/m3. assume
ideal behaviour and use r=8.314 j/mol. k.
your
answer

Explanation:

1) Data:

a) Chemical formula: (CH₃)₂CO

b) P = 100,000 Pa

c) T = 398 K

d) D = ?

e) R = 8.314 J / mol.K

2) Principles and formulae:

a) Ideal behaviour of a gas means that it follows the ideal gas equation:

b) Density, D = mass / volume

c) mass in grams = n × molar mass

3) Solution:

a) Transform the ideal gas equation to solve for the density:

b) Molar mass of (CH₃)₂CO: 58.08 g/mol

c) Substitute and compute:

* (note that by dividing by 1,000 the molar mass is transformed from g/mol to kg/mol)
