A solution of BCG (10mg/L) was used.
1.0 ml of BCG was added to 4.0 ml of water.
How do I find out the moles/litre for this?
Molecular weight of BCG is 698.

first: we find the weight of BCG when solution 1.0ml :
= 10mg/L x 1.0 X 10^(-3)L= 0.01 mg= 0.0001g
and we have the mole of BCG
the moles/litre is:
