To determine the mass of potassium (K) in 33.5 g of potassium chloride (KCl), you would need to understand the compound’s composition and use its molar mass. The quick calculation involves the following formula:<\/p>\n\n\n\n

Mass of Potassium (K) = Mass of KCL Molar Mass of KMolar Mass of KCL<\/p>\n\n\n\n

For KCl<\/strong>, the molar mass is 74.55 g\/mol<\/strong> (K: 39.10 g\/mol, Cl: 35.45 g\/mol). By substituting values, we can calculate the mass of potassium in 33.5 g of KCl.<\/p>\n\n\n\n

Step-by-Step Explanation<\/strong><\/p>\n\n\n\n

1. Understand the Composition of KCl:<\/strong><\/p>\n\n\n\n

Potassium chloride (KCl) is a binary ionic compound composed of potassium (K) and chlorine (Cl) in a 1:1 molar ratio. The molar mass of KCl is obtained by adding the atomic masses of K and Cl:<\/p>\n\n\n\n

Molar Mass of KCL = 39.10 g\/mol +34.45 g\/mol =74.55 g\/mol<\/p>\n\n\n\n

2. Calculate the Fraction of Potassium in KCl:<\/strong><\/p>\n\n\n\n

The percentage of potassium in KCl is given by:<\/p>\n\n\n\n

Fraction of K = Molar Mass of KMolar Mass of KCL = 39.1074.55 0.524<\/p>\n\n\n\n

This means potassium constitutes approximately 52.4%<\/strong> of the mass of KCl.<\/p>\n\n\n\n

3. Apply the Formula:<\/strong><\/p>\n\n\n\n

To find the mass of potassium in 33.5 g of KCl, multiply the total mass of KCl by the fraction of potassium:<\/p>\n\n\n\n

Mass of K = 33.5 g 0.524 17.54 g<\/p>\n\n\n\n

The mass of potassium in 33.5 g of KCl is approximately 17.54 g. This calculation is essential in analytical chemistry<\/strong>, especially when determining the elemental composition of compounds in reactions or industrial processes. <\/p>\n\n\n\n
