Calculate the mass percent by volume of 330.1 g of glucose (C₆H₁₂O₆, MM = 180.2 g/mol) in 325 mL of solution.
nadezda [96]

Answer: The mass percent by volume is 101.6%

Explanation:

The solution concentration expressed in percent by volume means that the amount of solute present in 100 parts volume of solution.

It is represented in formula as :

mass percent by volume =\frac{\text {mass of solute}\times 100}{\text {Volume of solution in ml}}\%

Given : mass of glucose = 330.1 g

volume of solution = 325 ml

Thus mass percent by volume =\frac{330.1g\times 100}{325ml}=101.6\%

Thus the mass percent by volume is 101.6%

Calculate the pH of the following aqueous solution:
Annette [7]

The pH of an aqueous solution that has a concentration of 0.35 M NaF and pKa for HF = 3.14 is 3.6.

<h3>How to calculate pH?</h3>

The pH of a solution refers to the degree of acidity or alkalinity of the solution. It can be calculated using the Henderson-Hasselbalch Equation as follows:

pH = pka + log ([A-]/[HA])

Where;

  • A- = conjugate base
  • HA = weak acid

pH = pKa + log([F-]/[HF])

pH = 3.14 + log(1/0.35)

pH = 3.14 + 0.4559 = 3.595

Therefore, the pH of an aqueous solution that has a concentration of 0.35 M NaF and pKa for HF = 3.14 is 3.6.
