2k+Cl2=2KCI how many grams of KCl is produced from 8.50 g of K and excess Cl2
ZanzabumX [31]

Answer:

Mass = 16.4 g

Explanation:

Given data:

Mass of K = 8.50 g

Mass of KCl produced = ?

Solution:

Chemical equation:

2K + Cl₂     →    2KCl

Number of moles of K:

Number of moles = mass/ molar mass

Number of moles = 8.50 g/ 39 g/mol

Number of moles = 0.22 mol

Now we will compare the moles of potassium and potassium chloride.

                  K         :        KCl

                  2         :          2

                0.22      :        0.22

Mass  of KCl:

Mass = number of moles × molar mass

Mass = 0.22 mol × 74.55 g/mol

Mass = 16.4 g
