Answer:
1.53 × 10²³ molecules As₂O₃
Explanation:
Step 1: Define
Diarsenic Trioxide - As₂O₃
Avagadro's number: 6.02 × 10²³ atoms, molecules, formula units, etc.
Step 2: Use Dimensional Analysis
= 1.52908 × 10²³ molecules As₂O₃
Step 3: Simplify
We have 3 sig figs.
1.52908 × 10²³ molecules As₂O₃ ≈ 1.53 × 10²³ molecules As₂O₃
Answer : The molarity of the chloride ion in the water is, 5.75 M
Explanation :
As we are given that 16.6 % chloride ion that means 16.6 grams of chloride ion present 100 grams of solution.
First we have to calculate the volume of solution.


Now we have to calculate the molarity of chloride ion.
Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.
Formula used :

Now put all the given values in this formula, we get:

Thus, the molarity of the chloride ion in the water is, 5.75 M
Chemical equations are equations that show that the chemical formulas of a substance that has been reacted and/or produced.
Nonrenewable energy resources include coal, natural gas, oil, and nuclear energy. Once these resources are used up, they cannot be replaced, which is a major problem for humanity as we are currently dependent on them to supply most of our energy needs
