🤓 Based on our data, we think this question is relevant for Professor Lunsford's class at PDX.

Determine the percent KCl in the mixture of KCl and KNO_{3} with 44.2% potassium by mass.

Step 1. Find the molar mass of KCl and KNO_{3}

Step 2. Assume that we have 44.2 g K, find the moles of K

Step 3. Establish a two unknown equation and find the mass % of KCl

Step 1. Find the molar mass of KCl and KNO_{3}

KCl** ****1** K × 39.10 g/mol K = 39.10 g/mol** 1**

Find the percent of KCl if a mixture of KCl and KNO3 is 44.2% potassium by mass.

A. 12%

B. 8%

C. 20%

D. 33%

E. 40%
