How do you solve a dilution problem in Chem?

Answer 1

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 represents the inital conditions (pre-dilution), and M2V2 denotes the final conditions (post-dilution).

Plug in the three values you know to find the fourth value, which you are solving for.

Ex.

750mLs of a 0.5 M NaC2H3O2 solution is diluted with 250mL of H2O. What is the new concentration of NaC2H3O2?

Answer:

(0.5M)x(.750L)=(MB)x(.750L+.250L)

0.375ML=(MB)x(1L)

MB=0.375M

Answer 2

To solve a dilution problem in chemistry, you typically use the formula M1V1 = M2V2, where M1 is the initial molarity, V1 is the initial volume, M2 is the final molarity, and V2 is the final volume. Plug in the values you have and solve for the unknown. Make sure to keep track of units and use appropriate conversion factors if needed.
