Calculate the molarity of a solution that contains 0.175 mol ZnCl2 in exactly 100 mL of solution.
what is .175/.1 ?
To calculate the molarity of a solution, you need to know the amount of solute (in moles) and the volume of the solution (in liters). Given that you have 0.175 mol of ZnCl2 and a volume of 100 mL (which needs to be converted to liters), we can use the formula:
Molarity (M) = moles of solute / volume of solution (in liters)
Step 1: Convert the volume from milliliters (mL) to liters (L):
Since 1 liter is equal to 1000 milliliters, we divide 100 mL by 1000 to get 0.1 L.
Step 2: Divide the moles of solute by the volume of solution:
Molarity (M) = 0.175 mol / 0.1 L
Step 3: Calculate the molarity:
Molarity (M) = 1.75 M
Therefore, the molarity of the solution is 1.75 M.
