Equations (learn) Flashcards
1
Q
mole calculations: mass
A
mass (g) = Mr X moles (n)
2
Q
gas calculations at RTP
A
volume (dm[-3]) = moles (n) X 24
3
Q
ideal gas equation
A
pV = nRT p = pressure in Pa V = volume in M[3] n = number of moles R = the gas constant 8.31Jk[-1]mol[-1] T = temperature in K
4
Q
mole calculations: concentration
A
concentration (moldm[-3]) = moles (n) / volume (dm[-3])
5
Q
cm[3] to dm[3]
A
1000cm[3] = 1dm[3]
6

A
1 mol = 6.022 X 10[23] atoms
8
Q
atom economy calculation
A
atom economy (%) = (mass of atoms in desired product / mass of all products) X 100
9
