The molarity of a sodium hydroxide solution is 0.2 M. The molar mass of NaOH is 40 g/mol.
If 20 g of sodium hydroxide (NaOH) is dissolved in water in this solution, what is the volume of the solution?
you have 1/2 mole in a volume.
.2M=.5/V
V=.5/.2=2.5Liters
Thank you bob
To find the volume of the sodium hydroxide solution, we can use the relationship between molarity, moles, and volume of the solution.
First, let's calculate the number of moles of NaOH that are present in the solution:
Number of moles (n) = mass (m) / molar mass (M)
n = 20 g / 40 g/mol
n = 0.5 mol
Now, we can use the definition of molarity to find the volume of the solution:
Molarity (M) = moles (n) / volume of solution (V)
0.2 M = 0.5 mol / V
Rearranging the equation, we can solve for the volume of the solution:
V = moles (n) / Molarity (M)
V = 0.5 mol / 0.2 M
V = 2.5 L
Therefore, the volume of the sodium hydroxide solution is 2.5 liters.
