223 grams of potassium chloride (KCl) can be produced from 356 g of potassium bromide.
Mass is the quantity of matter of a physical body.
The reaction is
[tex]\rm Cl_2 + 2KBr = Br_2 + 2KCI[/tex]
2 moles of KBr produces 2 moles of KCl
Step1 - calculating the moles of KBr
Molar mass of KBr = 119g/mol
Mass of KBr is 356 grams
[tex]\rm Number\;of \;moles= \dfrac{mass}{molar\;mass}\\\\\\\rm Number\;of \;moles= \dfrac{356}{119} = 2.99 mol[/tex]
Hence, there are two moles of KCl Mass of KCl will be
2.99 moles × 74.6g/mol = 223g.
Thus, 223 grams of potassium chloride (KCl) can be produced from 356 g of potassium bromide.
