Answer:
4.86×10^23 molecule of Pb
Explanation:
Based on that equation, for every 2 moles of ammonia, you get 3 moles of lead.
So:
2 mol NH3/ 3 mol Pb
Using this ratio we can find the amounts of either molecule. Given 5.38 mol NH3:
(5.38 NH3)(3 Pb/ 2 NH3) = (5.38)(3/2) mol Pb = 8.07 mol Pb
Then, we just need to use Avagadro's number to get the number of molecules.
(8.07)(6.02×10^23) = 4.86×10^23 molecule of Pb
Mass is not created or destroyed
Answer:
It is not dependent on the salt solute at all but the solute does have an affect.
Explanation:
in the equation you maybe aware of the I factor which represents the ions present in the solution. a non ionic will always have a I value of 1 a ionic can be 2 like in NaCl. What this means that all non ionic will lower the temperature depression but ionics will have a greater affect because for example salt breaks into Na and Cl will essentially hae more impurities than glucose which doesnt dissociate and will have a I value of 1
