Question

What is the molarity of 2 mol of calcium carbonate, CaCl2, dissolved in 1 L of solution?
HELP PLSS!!!!

Answer 1

Answer:

2mol/L

Explanation:

Given parameters:

Number of moles of calcium carbonate = 2mol

Volume of solution = 1L

Unknown:

Molarity  = ?

Solution:

The molarity of a solution is the number of moles of solute dissolved or contained in a solution:

 Molarity  = $\frac{number of moles }{volume }$  

 Molarity  = $\frac{2}{1}$   = 2mol/L
