The molar concentration of potassium ions in a  0. 250 m K₂SO₄(aq) solution is 2.

<h3>What is molar concentration?</h3>

The molar concentration of a solution is the presence of solute in one unit of a solution.

Molar concentration = number of moles / volume

The volume is given 0.250 m

To calculate the number of moles:

There will be 2 moles of potassium and  1 mole of sulfate in one L of the solution.

So in 0.250 L

0.250 x 2 x 1 = 0.500

The total number of moles of potassium and sulfate ion are 0.500

Now, putting the value:

Molar concentration = number of moles / volume

0.500 / 0.250 = 2

Thus, the molar concentration is 2.

2mL of a serum sample was added to 18mL of phosphate buffered saline (PBS) in Tube 1. 10mL of Tube 1 was added to 40mL of PBS in
Sladkaya [172]

Answer:

Tube 2 has a total dilution of 1:50

Explanation:

We have a 2 ml serum sample added to a 18 mL phosphate buffered saline sample in tube 1. This means now in tube 1 there is 20 mL.

We have a 1:10 (= 2:20) dilution here.

10 ml of this 1:10 diluted tube 1 is taken and added to a 40 mL of PBS in tube 2.

Now we have 50 mL in tube 2.

This is a 10:50 (= 1:5) dilution.

The total dilution is 10x5 = 50

So the total ditultion has a rate 1:50

Tube 2 has a total dilution of 1:50
