Answer: compound
Explanation:
Element is a pure substance which is composed of atoms of similar elements.It can not be decomposed into simpler constituents using chemical reactions.Example: Copper
Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.It can be decomposed into simpler constituents using chemical reactions. Example: water
Mixture is a substance which has two or more components which do not combine chemically and do not have any fixed ratio in which they are present. Example: Air
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.
