How to Calculate Dilution Problems
Dilution problems involve the process of making a less concentrated solution from a solution with a high level of concentration. Molarity is a unit that is used to indicate the concentration of a given solution. The unites of molarity are m... Read More »

How do you solve a dilution problem in Chem?
The key formula for solving a dilution problem is M1V1=M2V2 (alternately, MAVA=MBVB) where concentration is M (measured in Molars, a unite of concentration-->Molars=moles solute/Liters solution) and the volume of solution is V. M1V1 represe... Read More »

For these dilution problems, always use the equation: C1V1 = C2V2 Now substitute and solve for the unknown 0.340*55 = C2*545 C2 = 0.340*55/545 C2 = 0.0343M Amswer Final molarity = 0.0343M

The way to do serial dilutions is to take a fraction of your solution and add it to water to dilute the solute further. Since you start with 10mL of 12% salt, .04/.12= 1/3 meaning that you need to reduce your salt content down to 1/3 it's c...

you would solve this problem the same way you would solve any other dilution problem: Mconc*Vconc=Mdil*Vdil so Vconc=Mdil*Vdil/Mconc solve for the volumes desire of alcohol and chlorhexidine, add them together, and then dilute the rest with...

Think of it this way: 2.6x10^6 is the same as 260x10^4. To get it to 260 cells/mL requires performing tenfold serial dilutions four times. That means taking one mL of suspension and adding it to nine mL sterile dilution water, mixing it, an...

The final volume = 0.5mL + 2.8mL = 3.3mL Use dilution equation: M1V1 = M2V2 5*0.5 = M2*3.3 M2 = 2.5/3.3 M2 = 0.7575 M I would quote final concentration as 0.8mM taking sig figs into account.
