Well as it is 39.33% then go with a. also with 58.44 grams of NaCl you have 22.99 g Na so x100% = 39.33%

Answer:

Explanation:

Molecular mass of NaCl = 58.44g/mol

Molecular mass of Na = 22.98g/mol

Molecular mass of Cl = 35.5g/mol

To find the percentage mass of Na in NaCl we divide the molecular mass of Na by the total number of atoms of Na present in the compound which in this case is 1 by the molecular mass of the compound

%Na = molecular mass of Na / molecular mass of compound.

%Na =( 22.98 / 58.44 ) * 100

% Na = 0.3932 * 100 = 39.32%

The mass percent of Na present in NaCl is 39.32%

<em>Calculate the pH of the following substances formed during a volcanic eruption: </em>

<em>• Sulfurous acid if [H +] = 0.10 </em>

<em>• Nitric acid if [H +] = 0.11</em>

<em />

<h3>Further explanation </h3>

pH is the degree of acidity of a solution that depends on the concentration of H⁺ ions. The greater the value the more acidic the solution and the smaller the pH.

pH = - log [H⁺]
