The answer for the following problem is mentioned below.
- <u><em>Therefore the molarity of the solution is 3 × </em></u><u><em> M.</em></u>
Explanation:
Given:
mass of sodium hydroxide solution (NaOH) = 80.0 grams
Gram molecular mass of sodium hydroxide solution (NaOH) = 40.0 gram/mole
volume of the solution (v) = 6.00 L = 6000 ml
To find:
molarity of the solution (m)
We know,
m =
where,
m represents the molarity of the solution
n represents the no of moles
v represents the volume of the solution
we also know;
n =
where,
m represents the mass of the sodium hydroxide
M represents the Gram molar mass of the solution
So,
n =
n = 2
So,
m =
m = 3 × M
<u><em>Therefore the molarity of the solution is 3 × </em></u><u><em> M.</em></u>
