Answer:

2.3 M

Explanation:

First we calculate the final volume of the solution:

  • Final Volume = 200 mL + 700 mL
  • Final Volume = 900 mL

With the final volume we can use a <em>dilution factor</em> to c<u>alculate the concentration of the diluted solution</u>:

  • Original Concentration * Initial Volume / Final Volume = Final Concentration
  • 3 M * 700 mL / 900 mL = 2.3 M

fgiga [73]

The equation NaHco3+hc2h3o2=nac2h3o2+h2co3 is already balanced.

Reaction information:

Nahcolite + Acetic Acid = Sodium Acetate + Carbonic Acid

Reactants:

Nahcolite - NaHCO3 :

Molar Mass, Oxidation State

Acetic Acid - HC2H3O2

Molar Mass, Oxidation State, Ethanoic Acid, Methanecarboxylic Acid, Ch3-Cooh, Acetic Acid; Glacial, etc

(NaHCO3 + HC2H3O2 = NaC2H3O2 + H2CO3)
