What is the final concentration of the solution produced when 225.5 mL of 0.09988-M solution of Na2CO3 is allowed to evaporate u

ikadub [295]

Explanation:

The given data is as follows.

$V_{1}$ = 225.5 mL, $V_{2}$ = 45.00 mL

$M_{1}$ = 0.09988 M, $M_{2}$ = ?

Therefore, formula to calculate final concentration will be as follows.

$M_{1}V_{1}$ = $M_{2}V_{2}$

Putting the given values into the above formula as follows.

$M_{1}V_{1}$ = $M_{2}V_{2}$

$0.09988 M \times 225.5 mL$ = $M_{2} \times 45.0 mL$

$M_{2}$ = 0.5 M

Thus, we can conclude that the final concentration of the given solution is 0.5 M.

4. Calculate the final concentration if water is added to 1.5 L of a 12 M

konstantin123 [22]

Answer:

Explanation:

(Molarity x Volume)concentrated soln = (Molarity x Volume)diluted doln

Molarity dilute soln = [(M x V)conc/V (dilute)] = 1.5L x 12M / 3.0L = 6M final dilute soln
