Molar gas volume

Question 1

What is the definition of molar gas volume (Vm)?

Answer 1

The volume per mole of gas molecules at a stated temperature and pressure

Question 2

When does reacting volumes in gases take place?

Answer 2

Normally room temperature and pressure (RTP)

Question 3

What is RTP normally?

Answer 3

Room temperature - 25℃
Pressure - 101kPa

Question 4

What does 1 mole of gas molecules have a volume approximately of?

Answer 4

24.0dm³mol⁻¹
24,000cm³mol⁻¹

Question 5

How do you calculate the number of moles using the volume and molar gas volume?

Answer 5

Amount n (mol) = Volume (v) / Molar gas volume (Vm)

Question 6

How do you calculate the number of moles using the volume in dm3 and 24?

Answer 6

Moles (mol) = V (dm3) / 24

Question 7

How do you calculate the number of moles using the volume in cm3 and 24000?

Answer 7

Moles (mol) = V (cm3) / 24000

Question 8

How do you calculate the volume of a gas using the moles and 24000?

Answer 8

V (cm3) = n x 24000

Question 9

How do you calculate the volume of a gas using the moles and 24?

Answer 9

V (dm3) = n x 24
