Developing Fuels: Gas Calculations Flashcards
1
Q
Under standard conditions how do you work out the molar gas volume
A
No. of moles of compound within an equation
Eg. 3 H2 (g) = 3 mols = 3cm^3 mol has volume
2
Q
1 mole of any gas = ?
A
24dm^3
3
Q
1cm^3 = ?m^3
A
1cm^3 = 1 x 10^ -6 m^3
4
Q
1dm^3 = ?m^3
A
1dm^3 = 1 x 10^ -3 m^3
5
Q
1dm^3 = ?cm^3
A
1dm^3 = 1000cm^3
6
Q
What is the ideal gas equation
A
PV = nRT
7
Q
What does each letter stand for in PV = nRT
A
P = pressure ( Pa ) V = volume (m^3 ) n = moles of gas R = the gas constant ( given on periodic table ) T = temperature ( K )
8
Q
100kPa = ?Pa
A
100kPa = 100 000Pa
ie. x 1000
9
Q
25°c = ? K
A
25°c = 298 K
ie. 25 + 273
