Why do positive ions have a positive charge?​

Chemistry

Rudiy273 years ago

Answer:

Ions form when atoms gain or lose electrons. Since electrons are negatively charged, an atom that loses one or more electrons will become positively charged; an atom that gains one or more electrons becomes negatively charged. Ionic bonding is the attraction between positively- and negatively-charged ions.

The molar mass of KCl is 74. 55 g/mol. If 8. 45 g KCl are dissolved in 0. 750 L of solution, what is the molarity of the solutio
rosijanka [135]

Molarity is the strength of the solution or the ratio of the moles and the volume of the solution. The molarity of the solution is 0.1516 mol per Liter.

<h3>What is molarity?</h3>

Molarity is the molar concentration of the solution that tells about the amount of the solute or the substance dissolved in the given amount of the solution.

Given,

  • Mass of potassium chloride = 8.45 g
  • Molar mass of potassium chloride = 74. 55 g/mol
  • Volume of the solution = 0.750 L

Moles can be calculated by:

\begin{aligned}\rm Moles &= \rm \dfrac{Mass }{\rm Molar \;mass}\\\\&= \dfrac{8.45}{74.55}\\\\&= 0.1133\;\rm  mol\end{aligned}

Calculate molarity by:

\rm Molarity = \dfrac{moles}{\text{Volume in L}}

Substituting values in the equation:

\begin{aligned}\rm  Molarity &= \dfrac{0.1133}{0.750}\\\\&= 0.1516 \;\rm mol\;L^{-1}\end{aligned}

Therefore, the molarity of the solution is 0.1516 mol per Liter.
