   # Suppose you dilute 25.0 mL of a 0.110 M solution of Na 2 CO 3 to exactly 100.0 mL. You then take exactly 10.0 mL of this diluted solution and add it to a 250-mL volumetric flask. After Ailing the volumetric flask to the mark with distilled water (indicating the volume of the new solution is 250. mL), what is the concentration of the diluted Na 2 CO 3 solution? ### Chemistry & Chemical Reactivity

## Suppose you dilute 25.0 mL of a 0.110 M solution of Na2CO3 to exactly 100.0 mL. You then take exactly 10.0 mL of this diluted solution and add it to a 250-mL volumetric flask. After Ailing the volumetric flask to the mark with distilled water (indicating the volume of the new solution is 250. mL), what is the concentration of the diluted Na2CO3 solution?

Interpretation Introduction

Interpretation:

The concentration of Na2CO3 prepared by different volumes has to be determined.

Concept Introduction:

• Molarity: Amount of substance per litre of the solution
• Molarity=No.ofmolesVolumeofsolution(L)
• Preparing solution of known concentration:
• In order to prepare solution of known concentration, first we have to take the concentrated solution of known concentration and add solvent until the desired concentration is reached.

### Explanation of Solution

The amount of Na2CO3 in 25ml solution is:

AmountofNa2CO3=C×V=0.110mol×25×10-3L=2.75×10-3mol

Given that the solution is diluted to 100ml

We have to find out the amount of Na2CO3 in the new volume of 100ml

Finalconcentration=2.75×10-3mol0.100L=0
