Question

Given the following unbalanced equation: K+Cl2 -> KClHow many moles of KCl are produced from 2.50 moles K?

Answer 1

1) Balance the chemical equation

`2K+Cl_2\rightarrow2KCl`

2) Moles of KCl produced from 2.50 mol K.

The molar ratio between KCl and K is 2 mol KCl: 2 mol K.

`_{}molKCl=2.50molK\cdot\frac{2molKCl_{}}{2molK_{}}_{}=2.50molKCl_{}`

2.50 mol K will poroduce 2.50 mol KCl.
