Calculating Concentration in a Mixture of KNO3 and Fe3CN6

In summary, adding 20 ml of 1M Kno3 with 20 ml of 2 mM of Fe3CN6 will change the concentration of the two chemicals in the mixture. To calculate the new concentration, you need to multiply the volume of the original solution by the molarity of the solutes to find the total moles of each solute, and then divide that molar amount by the new volume. For example, 0.2L * 1M = 0.2 moles KNO3, and with a new volume of 40ml, the new concentration would be 0.2 moles / 0.04L = 5M.

hi,a basic question, i added 20 ml of 1M Kno3 with 20 ml of 2 mM of Fe3CN6. will the concentration of the two chemicals remain same in mixture?? if not how to calculate ... All i need to prepare a 20 ml of a mixture of 1M Kno3 and 2mM Fe3CN6...

Thanks

The concentration will change because you're changing the volume but not the molar amount. Multiply the volume of the original solution by the molarity of the solutes to find the total moles of each solute.

Ex-
0.2L * 1M = 0.2 moles KNO3

Then divide that molar amount by the new volume (40ml = 0.04L) to find the new concentration.

What is concentration in a mixture?

Concentration in a mixture refers to the amount of a particular component (usually a solute) in relation to the total amount of the mixture. It is often expressed as a percentage or in units such as moles per liter.

How is concentration measured in a mixture?

Concentration can be measured in a variety of ways, depending on the type of mixture and the component being measured. Some common methods include molarity, mass percent, and parts per million (ppm).

Why is concentration important in a mixture?

Concentration is important in a mixture because it affects the properties and behavior of the mixture. For example, a higher concentration of a solute can make a solution more acidic or basic, or affect its boiling and freezing points.

How does concentration change in a mixture?

The concentration in a mixture can change in several ways, including the addition or removal of a component, or through changes in temperature, pressure, or volume. It can also change as a result of chemical reactions between components in the mixture.

What factors can affect concentration in a mixture?

The concentration in a mixture can be affected by a variety of factors, including the amount and type of components present, the physical and chemical properties of those components, and external conditions such as temperature and pressure.
