Answer:
The answer is
Explanation:
To find the number of moles of NaCl we must first find it's molecular mass M after that we use the formula
[tex]n = \frac{m}{M} [/tex]
where
n is the number of moles
m is the mass
M is the molecular mass
From the question
m of NaCl = 15.6 g
M( NaCl ) = 22.99 + 35.45 = 58.44 g/mol
Substitute the values into the above formula and solve
That's
[tex]n = \frac{15.6}{58.44} \\ = 0.266940[/tex]
We have the final answer as
Hope this helps you
