Can someone help me in understanding the equations for finding molarity.
These are the equations that I’m given:
Moles of solute= (liters of solution) x (molarity of solution)
(Initial concentrations) x (initial volume) = (final concentration) x (final volume)
Or C1 V1 = C2 V2
Here is an example exercises if y’all need it to explain. No rush :)
1. Calculate the molarity of the solution.
29g of NaCl in 0.25 liters of water. (The molecular weight is 54.44 g/mole)
M
2. The molecular weight of NaCl is 58.44g/mol. If you had a 1.0 molar solution (1.0M), you would have to put 58.44g of salt in 1.0 liter of solution.
How many moles of NaCl would you have in 10.0 mL of this solution?
