Question

2 K + Cl2 → 2 KCI
How many grams of KCI (74.55 g/mol) is produced from 2.50 mol of K?

Answer 1

Answer: 186.3 g of
`KCl` will be produced from 2.50 mol of K

Step-by-step explanation:

The balanced chemical reaction is:

`2K+Cl_2\rightarrow 2KCl`

According to stoichiometry :

2 moles of K produce = 2 moles of
`KCl`

Thus 2.50 moles of
`K` will produce=
`(2)/(2)* 2.50=2.50moles` of
`KCl`

Mass of
`KCl=moles* {\text {Molar mass}}=2.50moles* 74.55g/mol=186.3g`

Thus 186.3 g of
`KCl` will be produced from 2.50 mol of K
