Well, students, so in this question, we are given with the reaction, which is the salsamic acid, one more of salsic acid is reacting with one mole of acidic and hydride to give one mole of aspirin.
00:13
And these m are the molar mass.
00:15
Okay, so molar mass of each of the compound is given.
00:17
We have been said that if the mass of salsalic acid and the acetic acid is given as 4 .939 grams for both, right, not both together, the different amounts.
00:28
So mass for acetic acid is 4 .939 grams and the mass of acetic acid is also 4 .939 grams.
00:35
Then you have to find out the mass for aspirin and the theoretical yield for aspirin.
00:39
So for this reaction, if we go to the in the form of chemical equations.
00:47
Okay.
00:47
So the chemical equations will be such as, if i write the chemical equation, it will be c7h6 .o3.
00:58
This is our what this is our cellic acid all right and this is reacting with c4 h3 h6 and this is our what this is our acidic acidic and hydride okay and this gives out aspirin aspirin is what c9 h8 o4 okay so this is our s p drain right and with this we get our ascetic acid also that is c2h4 o2 acetic acid acid all right so now to balance this equation you have to balance this equation so this is the balanced equation they have asked us about the mass is given and the molar mass is also given all right and you have to find out the mass of aspirin to find out the mass of aspirin so you can say that we have 138 .12 gram of salicylic acid of salicylic acid it gives us 180 .16 grams of aspirin.

All right...
