chawki said:From 2.5mole of lithium nitride, we have 2.5*3mole of LiOH
From 4.5mole of water , we have 4.5 mole of LiOH
Borek said:H2 + Cl2 -> 2HCl
You mix 1 mole of hydrogen and 1000000 moles of chlorine - how many moles of HCl would you get?
Borek said:Take a look at the reaction equation and stoichiometric coefficients.
How many moles of HCl can be produced from 1 mole of hydrogen? How many moles of Cl2 are needed for that? Do we have that much chlorine?
How many moles of HCl can be produced from 1000000 moles of chlorine? How many moles of H2 are needed for that? Do we have that much hydrogen?
Borek said:So, which one is a limiting reagent and what is the final answer?
chawki said:limiting reagent is H2O because the ratio Li3N/H2O = 1/3 =2.5/(3*2.5) = 2.5/7.5
we have too much H2O than we need
chawki said:so we will get 1.5 mol of NH3
Borek said:If water is a limiting reagent, we can't have too much of it.
Surprisingly, this is a correct answer. As I am not able to follow your line of thinking I am not convinced it is not accidental.
chawki said:so how many moles of HCl we get for mixing 1 mole of hydrogen and 1000000 moles of chlorine
chawki said:
ok well, isn't water the limiting reagent ?
I just watched that video and learned from it.
The chemical formula for lithium hydroxide is LiOH.
The molarity of a solution is calculated by dividing the moles of solute (in this case, lithium hydroxide) by the volume of the solution in liters. So, for a 0.602 mole solution of lithium hydroxide in 1 liter of solution, the molarity would be 0.602 M (moles per liter).
To calculate the number of moles, divide the given mass of lithium hydroxide by its molar mass. The molar mass of lithium hydroxide is 23.95 g/mol for lithium and 17.01 g/mol for hydroxide, so the total molar mass is 40.96 g/mol. Therefore, if you have 40.96 grams of lithium hydroxide, you have 1 mole of it.
To calculate the weight of 0.602 moles of lithium hydroxide, multiply the number of moles by its molar mass. 0.602 moles x 40.96 g/mol = 24.68 grams of lithium hydroxide.
The molarity of a solution is important in determining the concentration of a solute in a given volume of solution. This is useful in various scientific experiments and industrial processes where precise measurements of concentrations are necessary. In the case of lithium hydroxide, its molarity can also be used to determine the amount of acid needed to neutralize it in a chemical reaction.
