Q
what is the relative molecular mass Mr
A
Mr = sum of Ar of ALL its constituent atoms
2
Q
what is a mole
A
a mole of a substance is the amount of this substance equal to its Mr in grams
3
Q
how do you calculate mol
A
mol = mass / Mr
n = m / Mr
4
Q
how do you calculate concentration
A
conc = amount / volume.
c = n / v
5
Q
what is molarity
A
a measure of the concentration of a solution in the number of moles in 1L
6
Q
how do you calculate molarity
A
molarity = moles of solute / 1L of solvent
M = n / v
