Question

What are the values for % Cl and % F, respectively, for Sample II?

Answer 1

Answer:

Explanation:

The mass percentages of chlorine and fluorine:

  Given:

Mass of chlorine = 5.753g

 Mass of fluorine = 9.248g

Find the total of the masses given:

   Total mass = mass of chlorine + mass of fluorine = 5.753 + 9.248 = 15.001g

% of Cl = $\frac{mass of chlorine}{total mass}$ x 100

% of Cl = $\frac{5.753}{15.001}$ x 100 = 38.35%

% of F =  $\frac{mass of fluorine}{total mass}$ x 100

% of F =  $\frac{9.248}{15.001}$ x 100 = 61.65%
