## How do you make a 10% dilution?

For example, to make a 1:10 dilution of a 1M NaCl solution, you would mix one “part” of the 1M solution with nine “parts” of solvent (probably water), for a total of ten “parts.” Therefore, 1:10 dilution means 1 part + 9 parts of water (or other diluent).

## How do you do a 5 dilution?

Answer: 1:5 dilution = 1/5 dilution = 1 part sample and 4 parts diluent in a total of 5 parts. If you need 10 ml, final volume, then you need 1/5 of 10 ml = 2 ml sample. To bring this 2 ml sample up to a total volume of 10 ml, you must add 10 ml – 2 ml = 8 ml diluent.

## How do you make a 1/2 dilution?

For example, a 1:2 serial dilution is made using a 1 mL volume of serum. This expression indicates that 1 mL of serum is added to 1 mL of H20 and then mixed. This initial dilution is 1:2. Then, 1 mL of this dilution is added to 1 mL of H20 further diluting the sample.

## What would be the dilution if 96 ml of diluent is added to 4 ml of a bacterial suspension?

Therefore, when 4 ml of a bacterial suspension is added to 96 mL of diluent then the dilution of the resulting solution is 4 X .

## How would you produce a 10 2 dilution of a 5 ml?

A 10-2 dilution is a 100-fold dilution. So you need to take your 5 ml sample and add 495 ml water/PBS/medium to end up with an end volume of 500 ml.

## What is the dilution of 75 ml of diluent?

For the answer to the question above. I believe the answer to your question is “75/100 = 3/4” is the dilution needed for a 75ml of diluent added to 25ml of bacterial suspension.

## How do you calculate the concentration of water?

The standard state for a liquid is the pure liquid, so the standard state of water is pure water, whose concentration is 55.5 M (in a liter, there are 55.5 moles of water, so its concentration is 55.5 mol/L). In dilute aqueous solutions, the concentration of water is very close to 55.5 M.

## What is the concentration of a solution Class 9?

The concentration of a solution is the amount of solute present in a given quantity of the solution. The solution having small amount of solute is called Dilute Solution. The solution having large amount of solute is called Concentrated Solution.

## What is suspension example?

Ans: Common examples of suspension include the mixture of chalk and water, muddy water, the mixture of flour and water, a mixture of dust particles and air, fog, milk of magnesia, etc. Give the definition of suspension. Ans: A suspension is a heterogeneous mixture of two or more substances.

## What is the difference between solution and suspension?

Difference Between a Solution and a Suspension In a solution, the solute particles that are in the solvent are evenly mixed and so small that you can’t see them. In a suspension, the pieces of solute are large and can be seen floating throughout the solvent.
