Chemistry - The Mole

1.  MASS = MOL X MR

2. VOLUME = MOL X 24 DM3 

3. MASS(G) /MOL = CONC X VOLUME (IN DM3)

Empirical formula

Step 1:  Write down elements involved
Step 2: Write down the mass/percentage
Step 3: Write down Ar/Mr
Step 4:  Step 2 divide by 3
Step 5: Take the smaller value as the denominator
Step 6: Obtain empirical formula.

Molecular formula:

n   =     Mr / sum of…
