Question

2KI + Pb(NO3)2 → 2KNO3 + PbI2

Answer 1

Hello!

This question can be easily solved using the Mole Ratio of KNO₃/KI in the balanced reaction that is shown below:

2KI + Pb(NO₃)₂ → 2KNO₃ + PbI₂

The Mole Ratio of KNO₃/KI in this reaction is 2 moles KNO₃/ 2 moles KI so we can apply the following conversion factor:

$0,03 moles KI * \frac{2 moles KNO_3}{2 moles KI}=0,03 moles KNO_3$

So, if 0,03 moles of KI are completely consumed, 0,03 moles of KNO₃ are formed.

Have a nice day!
