Hello!
Molarity is defined as the number of moles of a substance that can be found in 1 liter of solution. That is expressed mathematically as
M=mol/LFor the FeCl₃ solution:

So, the concentration of this solution is
0,756 MHave a nice day!
1 liter = 1,000 milliliters
Would be considered as an iconic bond.
