A chemist must dilute of aqueous sodium carbonate solution until the concentration falls to . He'll do this by adding distilled water to the solution until it reaches a certain final volume. Calculate this final volume, in milliliters. Be sure your answer has the correct number of significant digits.

The question is incomplete, complete question is :

A chemist must dilute 73.9 mL of 400 mM aqueous sodium carbonate  solution until the concentration falls to 125 mM . He'll do this by adding distilled water to the solution until it reaches a certain final volume. Calculate this final volume, in liters. Be sure your answer has the correct number of significant digits.

The final volume of the solution will be 0.236 L.

Explanation:

Concentration of sodium carbonate solution before dilution =

Volume of sodium carbonate solution before dilution =

Concentration of sodium carbonate solution after dilution =

Volume of sodium carbonate solution after dilution =

Dilution equation is given by:

1 mL = 0.001 L

236 mL = 0.236 L

The final volume of the solution will be 0.236 L.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
