3. If you add an additional 750mL of pure water to the above solution of NH4HCO3, would the number of moles of NH4HCO3 in the total volume increase? Explain. Would this (500+750)mL solution of have a different concentration (M)? Explain. Derive a relationship between the initial concentration (Mi) of the 500mL(Vi) of the above solution with the final concentration (Mt) of the (500+750)mL(Vt) solution
