Explanation:
Remember that the formula for moles,
Therefore, we must first calculate the mass of
To do this, we can use the formula for density,
The density of sodium chloride is
So input:
Now we may use
The molar mass of sodium chloride is
So simply input:
Explanation:
Well, we'll need a few steps here...
First, know that
Now, we can use the density equation to find the mass of the sodium chloride:
The density of sodium chloride is
So, we have
Next, we have to use the molar mass formula to find the amount of moles.
The molar mass of sodium chloride is
So, our final answer is
