The volume of the gold chain is 4.18 cm³

<h3>What is density? </h3>

The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as

Density = mass / volume

With the above formula, we can determine the volume of the chain. Details below:

<h3>How to determine the volume of the gold chain</h3>

The following data were obtained from the question:

  • Mass of gold = 80.7 g
  • Density of gold = 19.3 g/cm³
  • Volume of gold chain =?

Density = mass /volume

Cross multiply

Density × volume = mass

Divide both sides by density

Volume = mass / density

Volume of gold chain = 80.7 / 19.3

Volume of gold chain = 4.18 cm³

A solution is prepared at that is initially in benzoic acid , a weak acid with , and in sodium benzoate . Calculate the pH of th
Kisachek [45]

Answer:

pH=4.1

Explanation:

Hello,

In this case, for a concentration of 0.42 M of benzoic acid whose Ka is 6.3x10⁻⁵ in 0.33 M sodium benzoate, we use the Henderson-Hasselbach equation to compute the required pH:

pH=pKa+log(\frac{[base]}{[acid]} )

Whereas the concentration of the base is 0.33 M and the concentration of the acid is 0.42 M, thereby, we obtain:

pH=-log(Ka)+log(\frac{[base]}{[acid]} )\\\\pH=-log(6.3x10^{-5})+log(\frac{0.33M}{0.42M} )\\\\pH=4.1

Regards.
