A67.8-g sample of srcl2 is dissolved in 111.5 ml of solution calculate the molarity of this solution

The molarity of a solution is the number of moles of solute present in the solution divided by the liters of solvent present in the solution. First, we find the moles and then convert the volume to liters.
Moles = mass / molecular mass
Moles = 67.8 / 158.53
Moles = 0.43 mol

One liter contains 1000 mL, so the volume is 0.115 L

The molarity of the solution = moles / liter
Molartiy = 0.43/0.115
Molarity = 3.74 M

The velocity would be 2
