Hey everyone in this question aquasulfuric acid reacts with solid sodium hydroxide to produce ecosodium sulfate and liquid water so what is the theoretical yield of sodium sulfate form from the reaction of 7 .8 gram of sulfuric acid and 2 .4 gram of sodium hydroxide so let us see the reaction so here sodium hydroxide 2 moles of sodium hydroxide solid react with the 1 mole of aquas sulfuric acid and it will produce one mole of aquas sodium sulfate and two mall of water liquid in this balanced chemical reaction so here's theoretical yield of sodium sulfate that we have to find out and the mass of sulfuric acid and mass of sodium hydroxide so both the masses of the reactants are given in this question.
01:01
So basically, first of all, we have to find out the limiting reactant.
01:05
So if data of more than one reactant is given, then first convert all the data into moles, then divided the malls of reactant with their respective stochometric coefficient.
01:15
So let us first find out the moles of the reactant, both sulfuric acid and sodium hydroxide.
01:21
And we know number of moles can be calculated by using this simple formula that is equal to mass upon molar mass.
01:27
So number of mall of sulfuric acid that is equal to mass of sulfuric acid upon molar mass of sulfuric acid.
01:33
Substitute the value.
01:35
So we get the value 0 .0796.
01:38
So moles of sulfuric acid, 0 .0796 molts.
01:43
And similarly, molts of sodium hydroxide can be calculated by using the same formula.
01:49
And now substitute the value of mass of sodium hydroxide, which is 2 .4 gram and molar mass of sodium hydroxide, which is 40 gram per mole.
01:56
So we get the value of moles of sodium hydroxide which is 0 .06 moles.
02:03
Now number of mole upon stochometric coefficient.
02:06
So you can see the stochometric coefficient of sulfuric acid that is one.
02:11
So stochometric coefficient of sulfuric acid 1 and this stochometric coefficient of sodium hydroxide that is 2.
02:18
So number of mall upon stockometric coefficient in case of sulfuric acid that comes out to be 0 .0796 and number of molecule upon stochometric in case of sodium hydroxide that comes out to be 0 .03...
