Moles of potassium nitrate produced : 0.76
Further explanation
The reaction equation is the chemical formula of reagents and product substances
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
Reaction
2KI + Pb(NO₃)₂ ⇒ 2KNO₃ + Pbl₂
MW KNO₃ : 101.1032 g/mol
MW Pbl₂ = 461,01 g/mol
175 grams of Pbl₂ , mol :
[tex]\tt mol=\dfrac{175}{461.01}=0.38[/tex]
mol ratio KNO₃ : Pbl₂ = 2 : 1, so mol KNO₃ = 0.38 x 2 = 0.76
Mass of KNO₃ :
[tex]\tt mass=0.76\times 101.1032=76.838~g[/tex]
