Answer:
A) 0.50 M
Explanation:
The computation of the number of molarity of the NaOH is given below:
As we know that
Molarity = Moles ÷ liters
where
Moles is 20
And, the liters is 40
So, the molarity is
= 20 ÷ 40
= 0.50 M
hence, the molarity of the NaOH solution is 0.50 M
Therefore the A option is correct
You have molarity and you have volume. Use the formula :
Molarity(M)= Moles(N)/Liter(L) to get the solution.
150 ml= .150 L
7.7 = N/.150
N=.1.155 moles of NaOH.
And since you know the moles, use the molar mass to figure out the grams.
<span> (40g/mol NaOH) x (1.155mol) =
46.2 g of NaOH.</span>
All of the above
if that is not one of the choices, then A. local government
