molarity of the sodium nitrate solution = 0.496 ≈ 0.5 M
Explanation:
First we need to determine the number of moles of sodium nitrate (NaNO₃).
number of moles = mass / molecular weight
number of moles of sodium nitrate = 5.31 / 85 = 0.062 moles
Now we determine the molarity of the solution with the following formula:
molarity = number of moles / solution volume (L)
molarity of the sodium nitrate solution = 0.062 / 0.125 = 0.496 ≈ 0.5 M

Answer:
<h3>The answer is 0.79 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of ethyl alcohol = 63.3 g
volume = 80 mL
The density is
We have the final answer as
<h3>0.79 g/mL</h3>
