To solve this problem, we can use the formula for dilution:<br /><br />C1V1 = C2V2<br /><br />Where:<br />C1 = initial concentration<br />V1 = initial volume<br />C2 = final concentration<br />V2 = final volume<br /><br />Given information:<br />- Initial concentration (C1) = 0.009988 M<br />- Initial volume (V1) = 225.5 mL<br />- Final volume (V2) = 45.00 mL<br /><br />Substituting the values in the formula:<br /><br />C1V1 = C2V2<br />(0.009988 M)(225.5 mL) = C2(45.00 mL)<br />C2 = (0.009988 M)(225.5 mL) / (45.00 mL)<br />C2 = 0.0502 M<br /><br />Therefore, the final concentration of the solution produced when 225.5 mL of a 0.009988 M solution of Na2CO3 is allowed to evaporate until the solution volume is reduced to 45.00 mL is 0.0502 M.
