the mole Flashcards
1
Q
the gram formula mass (GFM) of a substance is
A
the mass of 1 mole of that substance
2
Q
how to calculate GFM:
A
add all the relative atomic masses together
multiply if there is more than 1 atom
3
Q
mass equation:
A
m = n x GFM
4
Q
no. of moles equation:
A
n = m divided by GFM
5
Q
moles are used to calculate
A
concentrations of a solution
6
Q
a solution is produced when a
A
solute dissolves in a solvent
7
Q
no. of moles calculation:
A
n = c x v (divided by 1000)
8
Q
concentration calculation:
A
c = n divided by v
9
Q
volume calculation:
A
v = n divided by c
