Question

what is the molarity of the solution formed by mixing 0.20 mol of sodium hydroxide with enough water to make 150 ml of solution?

Answer 1

To find the molarity of the solution, we need to use the formula:

Molarity (M) = moles of solute / liters of solution

In this case, we have 0.20 moles of sodium hydroxide (NaOH) and 150 mL of solution. However, the formula requires liters, not milliliters, so we need to convert 150 mL to liters by dividing by 1000:

150 mL / 1000 = 0.150 L

Now we can plug in the values and solve for molarity:

Molarity (M) = 0.20 moles / 0.150 L

Molarity (M) = 1.33 M (rounded to 2 decimal places)

So the molarity of the solution formed by mixing 0.20 mol of sodium hydroxide with enough water to make 150 mL of solution is 1.33 M.

Answer 2

The molarity is 1.33 M
