Question:

What mass of potassium chloride, a salt substitute often used by heart patients, can be produced directly from {eq}5.2 \ g {/eq} potassium and {eq}7.9 \ g {/eq} chlorine ?

{eq}2 K + Cl_2 \longrightarrow 2 KCl {/eq}

(a) {eq}5.2 \ g \ KCl {/eq}

(b) {eq}4.9 \ g \ KCl {/eq}

(c) {eq}9.9 \ g \ KCl {/eq}

(d) {eq}10.1 \ g \ KCl. {/eq}

Stoichiometry:

The determination of quantity that gets finished or yielded in any reaction is accomplished by utilizing the existing stoichiometric ratio. The numeric value present with the species addresses the stoichiometric ratio.
