80.0 grams of NaOH is dissolved in water to make a 6.00 L
solution. What is the molarity of the solution? (Molar mass of
NaOH = 40.0 g/mol) _M

The answer for the following problem is mentioned below.

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

Therefore the molarity of the solution is 3 × M.
