1.) 1 mol of NH₄HCO₃ = ______ mol of N + ________ mol of H + ______ mol of C + ______mol of O

1 mol NH₄HCO₃ = _____ g NH₄HCO₃

_2.)

Molarity (M) calculation

M = mol of solute/L of solvent

Information known:

Molar mass of NH₄HCO₃ = 79 g/mol

Volume of solution = 500 mL

M of solution = 0.5 M

What information need to be calculated to find g of NH₄HCO₃? Show complete calculation for g of NH₄HCO₃

_3.) If you add an additional 750 mL 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.

4.)Derive a relationship between the initial concentration (M_i) of the 500 mL (V_i) of the above solution with the final concentration (M_f) of the (500 + 750) mL (V_f) solution.
