The forensic technician at a crime scene has just prepared a luminol stock solution by adding 15.0 gg of luminol into a total vo
Firdavs [7]

Answer:

1.13 M

Explanation:

Given data

  • Mass of luminol (solute): 15.0 g
  • Volume of solution = volume of water = 75.0 mL = 0.0750 L
  • Molar mass of luminol: 177.16 g/mol

The molarity of the stock solution of luminol is:

M = mass of solute / molar mass of solute × liters of solution

M = 15.0 g / 177.16 g/mol × 0.0750 L

M = 1.13 M

Tasya [4]

Based on the bond length, the molecular weight of the unknown metal X is 23.

<h3>What are ionic compounds?</h3>

Ionic compounds are compounds which are formed between oppositely charged ions.

When hydrogen combines with the group 1 metals, they form ionic compounds.

The group one metals that combine with hydrogen to firm ionic bonds include:

  • Lithium to give Lithium hydride with equilibrium bond length of 0.239Å.
  • Sodium to give sodium hydride with equilibrium bond length of 1.896Å.
  • Potassium to give potassium hydride with equilibrium bond length of 2.321Å

The molecular weight of lithium is 7 g

The molecularweight of sodium is 23

The molecular weight of Potassium is 39.

Therefore, based on the equilibrium bond length, the molecular weight of the unknown metal X is 23.
