How many mg of metallic ions are in 1.0 mL of 0.10 M LINO3
Anton [14]

Answer:

0.6941 mg

Explanation:

First we <u>calculate how many LiNO₃ moles there are</u>, using the <em>given concentration and volume</em>:

  • 1.0 mL * 0.10 M = 0.10 mmol LiNO₃

As 1 mol of LiNO₃ contains 1 mol of Li,<em> in the problem solution there are 0.10 mmol of Li</em> (the only metallic ion present).

Now we<u> convert Li milimoles into miligrams</u>, using its <em>atomic mass</em>:

  • 0.10 mmol Li * 6.941 mg/mmol = 0.6941 mg

If the absorbance of a KMnO4 solution of unknown concentration is 0.633, calculate the concentration of KMnO4 in the solution.
solong [7]

The molar Concentration of KMnO₄ is 0.000219 M

Concentration is the abundance of a constituent divided by means of the overall extent of an aggregate. numerous styles of mathematical description may be outstanding: mass awareness, molar awareness, variety concentration, and quantity awareness.

y is absorbance

x is the molar concentration of KMnO_4

y = 4.84E + 03x - 2.26E - 01

0.833 = 4.84 * 10⁺⁰³ x - 2.26 * 10⁻¹

1.059 = 4.84 * 10⁺⁰³ x

X = 0.000219 M

Hence, The molar Concentration of KMnO₄ is 0.000219 M
