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

 186.3 g of will be produced from 2.50 mol of K

Explanation:

The balanced chemical reaction is:

According to stoichiometry :

2 moles of K produce = 2 moles of

Thus 2.50 moles of will produce=  of

Mass of

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