Answer:
The concentration of chloride ion is
Explanation:
We know that 1 ppm is equal to 1 mg/L.
So, the content 100 ppm suggests the presence of 100 mg of
in 1 L of solution.
The molar mass of is equal to the molar mass of Cl atom as the mass of the excess electron in
is negligible as compared to the mass of Cl atom.
So, the molar mass of is 35.453 g/mol.
Number of moles = (Mass)/(Molar mass)
Hence, the number of moles (N) of present in 100 mg (0.100 g) of
is calculated as shown below:
So, there is of
present in 1 L of solution.

Answer:
<h2>The answer is 2.52 g/mL</h2>Explanation:
The density of a substance can be found by using the formula
From the question
mass of object = 15.9 g
volume = final volume of water - initial volume of water
volume = 56.3 - 50 = 6.3 mL
It's density is
We have the final answer as
<h3>2.52 g/mL</h3>Hope this helps you
