Calculate the molarity (M) of a solution if you have 0.34 mol of NaOH in 19 ml of water
molarity is moles/liter
.34 moles/.019 liter = 17.9M
To calculate the molarity (M) of a solution, we need to divide the number of moles of solute by the volume of the solution in liters.
Given:
Number of moles of NaOH (solute) = 0.34 mol
Volume of water (solution) = 19 ml
First, we need to convert the volume from milliliters (ml) to liters (L):
19 ml = 19/1000 L = 0.019 L
Now, we can calculate the molarity (M):
Molarity = moles of solute / volume of solution
M = 0.34 mol / 0.019 L
M ≈ 17.9 M
Therefore, the molarity of the solution is approximately 17.9 M.
To calculate the molarity (M) of a solution, you need to divide the number of moles of the solute by the volume of the solution expressed in liters.
Given:
Number of moles of NaOH (solute) = 0.34 mol
Volume of the solution = 19 mL
Step 1: Convert the volume from milliliters (mL) to liters (L).
Since 1 L is equal to 1000 mL, divide the volume in mL by 1000.
19 mL ÷ 1000 = 0.019 L
Step 2: Use the molarity formula.
Molarity (M) = Moles of solute (mol) ÷ Volume of solution (L)
Substitute the given values:
Molarity (M) = 0.34 mol ÷ 0.019 L
Step 3: Calculate the molarity.
Molarity (M) = 0.34 ÷ 0.019 ≈ 17.89 M
Therefore, the molarity of the solution is approximately 17.89 M.
