You will need 10.773 grams of sodium acetate and 178.23 mL of water.
What is a solution?
A solution is a homogenous mixture of a solute and a solvent. When two substance mixes perfectly together makes a solution.
Given, that the density of water is 1.00 g/mL.
Preparation of 189 grams of 5.70 % solution.
Mass of CH₃COONa
189 x 5.70 / 100 = 10.773 grams
Mass of water = mass of solution – mass of solute
189 - 10.77 = 178.23 grams
Volume = mass / density
178.23 / 1.00 = 178.23 ml
Thus, the mass of sodium acetate is 10.773 grams, and the volume of water is 178.23 ml.
