Molarity or molar concentration is a measure of the concentration of a chemical species, of a solute in a solution, using as units, number of moles, and volume in liters. The formula for Molarity is:
M = n/V
Where:
n = number of moles, 1.7 moles
V = volume in Liters, 2.8 Liters
Now we add these values into the formula:
M = 1.7/2.8
M = 0.61
The Molarity is 0.61 M
