(a)
Interpretation:
The preparation of 250 mL of 3.6% w/v solution of NaCl in water should be explained.
Concept Introduction:
The concentration is shown as w/v meaning this is mass of solute per volume of solution.
Answer to Problem 6.36P
Explanation of Solution
Given Information:
Concentration has several ways to be calculated. It typically relates an amount of solute and the solution. Then given in mass of solute per unit volume of solution, or w/w, the total mass of the solute, solvent and solution must be known.
The formula for w/v is given as:
Substitute known data and solve for mass of solute.
Thus,
(b)
Interpretation:
The preparation of solution should be explained.
