Mole-Mass and Mole-Volume Relationships

Mole-Mass and Mole-Volume Relationships. The Mole-Mass Relationship. To convert the mass of a substance to the number of moles of the substance you have to use the molar mass of an element or compound. Mass = # of moles x (mass/1mole). The Mole-Mass Relationship.

Mixing Solutions

Mixing Solutions. That have something in common. Calculate the final concentration if 1 .00 L of 2 .00 M CaBr 2 and 3 .00 L of 1.50 M CaBr 2 are mixed. To find the final concentration(Molarity), we need total moles and total volume (litres). 2.00M = moles 1.50M = moles
