Answer:

Forces inside the atom

The atom is comprised of three major particles—protons, neutrons and electrons. There are four forces (Electromagnetic, Strong, Weak, and Gravity) that are responsible for the behavior of the particles and thus keep the atom together.

A chemist prepares a solution of iron chloride by measuring out 0.10 g of FeCl2 into a 50. mL volumetric flask and filling to th

Tanya [424]

Answer: The molarity of anions $(Cl^-)$ in the solution is 0.0316 M

Explanation:

To calculate the molarity of solution, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}$

We are given:

Given mass of iron (II) chloride = 0.10 g

Molar mass of iron (II) chloride = 126.75 g/mol

Volume of solution = 50 mL

Putting values in above equation, we get:

$\text{Molarity of iron (II) chloride}=\frac{0.10\times 1000}{126.75\times 50}\\\\\text{Molarity of iron (II) chloride}=0.0158M$

1 mole of iron (II) chloride produces 1 mole of $Fe^{2+}$ ions and 2 moles of $Cl^-$ ions

So, concentration of chloride ions (anions) in the solution = $(2\times 0.0158)=0.0316M$

Hence, the molarity of anions $(Cl^-)$ in the solution is 0.0316 M
