Answer: 186.3 g of [tex]KCl[/tex] will be produced from 2.50 mol of K
Explanation:
The balanced chemical reaction is:
[tex]2K+Cl_2\rightarrow 2KCl[/tex]
According to stoichiometry :
2 moles of K produce = 2 moles of [tex]KCl[/tex]
Thus 2.50 moles of [tex]K[/tex] will produce=[tex]\frac{2}{2}\times 2.50=2.50moles[/tex] of [tex]KCl[/tex]
Mass of [tex]KCl=moles\times {\text {Molar mass}}=2.50moles\times 74.55g/mol=186.3g[/tex]
Thus 186.3 g of [tex]KCl[/tex] will be produced from 2.50 mol of K
