Molarity
« on: February 14, 2015, 12:01:25 PM »
I have 0.04 mol.
I need to calculate the molarity of my solution (100mL of water and 2.50g of NaCl)
0.04/100mL+2.5g
=0.00039024
Is this correct?

You need to be a bit more specific about your units. You have 0.04 moles of what? What is 0.00039024?

Molar concentration is usually moles per litre (c=n/V). What is the molecular weight of NaCl and H2O?
