A 50 mL sample of 0.85 mol/L NaHCO3 is diluted to a volume of 250 mL. Then a 50.0 mL sample of this dilute solution is evaporated to dryness. What mass of NaHCO3 remains?

I have no idea how to tackle this question. Any help would be really appreciated.

Do you know how to calculate the molarity of your diluted sample?
