Question

What is molarity of a solution containing 0.34 moles of FeCl3 in the 0.45 liters of water

Answer 1

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/L

For the FeCl₃ solution:


`M= (mol FeCl_3)/(L sol)= (0,34 moles FeCl_3)/(0,45 L)= 0,756 M`

So, the concentration of this solution is 0,756 M

Have a nice day!
