Question

A chemist prepares a solution of zinc nitrate (Zn(NO3)2) by measuring out 280 g of zinc nitrate into a 350 mL volumetric flask and filling the flask to the mark with water. Calculate the concentration in mol/L of the chemist's zinc nitrate solution. Be sure your answer has the correct number of significant digits.

Step 1

First, we need to find the molar mass of zinc nitrate (Zn(NO3)2). The molar mass of Zn = 65.38 g/mol The molar mass of N = 14.01 g/mol The molar mass of O = 16.00 g/mol So, the molar mass of Zn(NO3)2 = 1 * 65.38 + 2 * (1 * 14.01 + 3 * 16.00) Show more…
