Molarity is defined as the moles of solute per liter of solution. 
. Where M is molarity, n is the number of moles and V is the volume. First we must find the molar mass of 
which is 109.98 g/mol
Then we find the molarity using above equation
Answer:
Molarity indicates the number of moles of solute per liter of solution and is one of the most common units used to measure the concentration of a solution.
