D the answer is d at least as read the answer
Quantity of the substance, moles
4.4
Molar mass of the substance
18.0
Just did this question on Mastering Chem, it's 1
Answer:
The answer is
<h2>1.20 L</h2>
Explanation:
Since the concentration , mass and molar mass of NaOH has been given we use the formula
<h3>

</h3>
To find the volume
where
C is the concentration
m is the mass
M is the molar mass
v is the volume
Making volume the subject we have
<h3>

</h3>
From the question
C = 1.25 M
m = 60 g
M = 40.0 g/mol
Substitute the values into the above formula and solve for the volume
We have
<h3>

</h3>
We have the final answer as
<h3>Volume = 1.20 L</h3>
