Compare Solution X to Solution A, Solution B, and Solution C. Beaker with a zoom view showing eight shperes, four groups of particles each consisting of two differently colored spheres. Beaker with a zoom view showing four spheres of a single color Beaker with a zoom view showing eight spheres of a single color Beaker with a zoom view showing eight shperes, two groups of particles each consisting of four spheres, three of one color and one of a different color. Which of the solutions have the same molar concentration as Solution X? C

Respuesta :

Answer:

SOLUTION A

Explanation:

Molarity is one of the most common measure of concentration

The correct option that gives the solution that has the same molar concentration as solution X is the option;

Solution A

Reason:

The descriptions of the content or each beaker are;

Content of beaker X = Eight spheres of four groups of two differently colored spheres

Content of beaker with solution A = Four spheres of a single color

Content of beaker with solution B = Eight spheres of a single color

Content of beaker with solution C = Eight spheres in two groups of four having three spheres of one color and one sphere of a different color

The concentration of a solution given by the molarity is defined as the    number of moles per liter of the solution

A mole is a quantity of matter that contains 6.023 × 10²² elementary particles

Considering each group of spheres as representing one mole of a substance, we have;

  • Beaker with solution X contains, Four moles containing two elements each, per volume of the solution, such as HCl
  • Beaker with solution A contains, four moles of a single (one) element compound per volume of the solution
  • Beaker with solution B contains, eight moles of a compound having one element each
  • Beaker with solution C contains, two moles having four elements each, three of one type and one of another element, such as CH₃

Therefore, the solution that has the same molar concentration, (the same number of moles per volume of the solution) is solution A
