Question

A chemist prepares a solution of zinc nitrate ( left(mathrm{Zn}left(mathrm{NO}_{3} ight)_{2} ight) ) by measuring out ( 0.507 mathrm{~kg} ) of zinc nitrate into a 450 . mL volumetric flask and filling the flask to the mark with water. Calculate the concentration in ( mathrm{mol} / mathrm{L} ) of the chemist's zinc nitrate solution. Be sure your answer has the correct number of significant digits. ( square mathrm{mol} / mathrm{L} )

Step 1

To do this, first, we need the molar mass of zinc nitrate (\(\mathrm{Zn(NO_3)_2}\)). The molar mass can be calculated as follows: - The atomic mass of zinc (Zn) is approximately 65.38 g/mol. - The atomic mass of nitrogen (N) is approximately 14.01 g/mol. - The Show more…
