A 10.0 ml aliquot is removed from the described stock solution and diluted to a total volume of 100.0 ml. calculate the molarity
Montano1993 [528]

1. The molarity of the stock solution is 1.26 M

2. The molarity of the diluted solution is 0.126 M

<h3>1. How to determine the molarity of stock solution </h3>

From the question given above, the following data were obtained

  • Mole of KIO₃ = 6.05 mole
  • Volume = 4.8 L
  • Molarity of stock solution =?

Molarity = mole / Volume

Molarity of stock solution = 6.05 / 4.8

Molarity of stock solution = 1.26 M

<h3>2. How to determine the molarity of the diluted solution </h3>
  • Molarity of stock solution (M₁) = 1.26 M
  • Volume of stock solution (V₁) = 10 mL
  • Volume of diluted solution (V₂) = 100 mL
  • Molarity of diluted solution (M₂) =?

M₁V₁ = M₂V₂

1.26 × 10 = M₂ × 100

12.6 = M₂ × 100

Divide both side by 100

M₂ = 12.6 / 100

M₂ = 0.126 M

An aqueous potassium iodate stock solution is made by dissolving 6.05 mol KIO3 in sufficient water for the final volume of the solution to be 4.80 L.

Calculate the molarity of the stock KIO3 solution.

A 10.0 mL aliquot is removed from the described stock solution and diluted to a total volume of 100.0 mL.

Calculate the molarity of the dilute solution

devlian [24]

Answer:

The answer is "9 inch".

Explanation:

Equation:

\to x+3x+2x=18 \ inch \\\\ \to 6x=18 \\\\  \to x= \frac{18}{6} \\\\ \to x=3 \ inch  \\\\

The highest amount of a bottle of shampoo that can stand upright on the central shelf:

=3x \\\\=3 \times 3 \\\\=9 \ inch

Calcium absorption is decreased by quizlet
Andrej [43]

What can cause a decrease in calcium absorption is; High Levels of Sodium

<h3>What causes poor calcium absorption?</h3>

Calcium absorption varies by type of food. The absorption of calcium from dairy products and fortified foods is about 30%.

Some compounds in plants like oxalic acid and phytic acid can decrease calcium absorption by forming indigestible salts with calcium, thereby decreasing its absorption.

Now, we can conclude that calcium absorption is decreased by high levels of sodium because excessive salt can interfere with calcium absorption.
