H
Since K stands for potassium, C stands for Carbon and O stands for Oxygen
14 since K has 1 valence but there’s two so 2 valence for k and oxygen has 6 but there’s two so 12
The force of an object due mass and gravity.it can also be defined as the force exerted by gravity on a body
Molarity is the molar concentration of the solute dissolved in a volume of a solution. The molarity of the solution prepared by dissolving barium chloride will be 0.085 M.
<h3>What is molarity?</h3>
Molarity is the ratio of the moles of the solute to that of the volume of the solution in Liters. It can be given as,

Here, moles of the barium chloride can be given by the mass and the molar mass and volume is given as 0.450 L.
Substituting values in the equation:

Therefore, 0.085 M barium chloride is the molar concentration.
