If 20 mole of potassium react with an excess of lithium sulfate , how many moles of potassium sulfate can you expect to form.
porassium phosphate to potassium sulfate: 20 x 2 kaso4 x 174.259 / 212.267 /2 = 16.4188498448
lithium sulfate to potassium sulfate: 62 x 2kaso4 x 174.259 / 109.94 /3 = 65.5148747802
i don't know which which would expect to form
To determine which compound would be expected to form when 20 moles of potassium (K) react with an excess of lithium sulfate (Li2SO4), we can compare the stoichiometric ratios of the reacting compounds.
First, we need to write the balanced chemical equation for the reaction:
2K + Li2SO4 -> ???
From the equation, we can see that for every 2 moles of potassium (2K), we need 1 mole of lithium sulfate (Li2SO4) to react.
Given that we have an excess of lithium sulfate, we can assume that the limiting reactant is potassium. This means that all the potassium will be completely consumed in the reaction, and the amount of product formed will be determined by the stoichiometry of the reaction.
To determine the number of moles of potassium sulfate (K2SO4) formed, we can use the stoichiometric ratio between potassium and potassium sulfate:
2K -> 1K2SO4
Therefore, for every 2 moles of potassium reacted, we would expect to form 1 mole of potassium sulfate.
Since we have 20 moles of potassium, we can calculate the moles of potassium sulfate formed as follows:
20 moles of potassium x (1 mole of K2SO4 / 2 moles of K) = 10 moles of K2SO4
So, if 20 moles of potassium react with an excess of lithium sulfate, we would expect to form 10 moles of potassium sulfate.
Based on the given information, we know that 20 moles of potassium react with an excess of lithium sulfate. However, it is unclear which compound we are trying to find the number of moles for; whether it is potassium phosphate or potassium sulfate.
Could you please clarify which compound you are referring to?
