calculate the molarity of a solution containing 0.5050 mol of solute in 400.0 ml of solution
To calculate the molarity of a solution, you need to know the number of moles of solute and the volume of the solution in liters.
In this case, we have 0.5050 mol of solute and 400.0 ml of solution. However, molarity is typically reported in liters, so we need to convert the volume from milliliters to liters by dividing it by 1000.
Volume of solution in liters = 400.0 ml / 1000 = 0.4000 L
Now we can calculate the molarity using the formula:
Molarity (M) = moles of solute / volume of solution (in liters)
Molarity (M) = 0.5050 mol / 0.4000 L = 1.2625 M
Therefore, the molarity of the solution is 1.2625 M.
