a chemist prepares a solution of zinc oxalate (znc₂o₄) by weighing out 6.701 g of zinc oxalate into a 400. ml volumetric flask and filling the flask to the mark with water. calculate the concentration in g/ml of the chemists zinc oxalate solution. be sure your answer has the correct number of significant digits.

Answer

Explanation:

Step1: Identify the formula for concentration

Concentration ( C=\frac{m}{V} ), where ( m ) is the mass and ( V ) is the volume.

Step2: Substitute the given values

Given ( m = 6.701\ g ) and ( V=400\ mL ). Then ( C=\frac{6.701\ g}{400\ mL} ).

Step3: Calculate the value

( C = 0.0167525\ g/mL\approx0.0168\ g/mL ) (rounded to three significant digits as 6.701 has four significant digits and 400 has one, but in the context of a volumetric flask, 400. (assuming the decimal is implied) would have three significant digits. Here we go with three as a common - sense approach for such lab - related problems).

Answer:

( 0.0168\ g/mL )
