Equations Flashcards
1
Q
N(moles)
A
Mass(g)/molar mass
2
Q
Volume at R.T.P
A
N(moles) x 24
3
Q
Ideal gas equation
A
Pv=nRT
Pressure x volume = moles x 8.314 x temperature kelvins
4
Q
Concentration
A
Moles / volume (dm3)
5
Q
Concentration ( gdm(-3))
A
Concentration( mol dm(-3)) x molar mass
6
Q
How do you convert to kelvins?
A
Degrees + 273
7
Q
How do you convert volume?
A
M3 - dm3 = x1000
Dm3 - cm3 = x1000
Cm3 - Dm3 = /1000
Dm3 - M3 = /1000
8
Q
How do you covert pressure?
A
Kpa- pa= x1000
9
Q
How do you convert concentration?
A
Mol cm-3 - mol dm-3 = x1000
10
Q
Number of particles
A
N(moles) x Na (6.02x10(23))
