Answer : The percent yield of the reaction is, 75.6 %
Solution : Given,
Mass of Pb = 451.4 g
Molar mass of Pb = 207 g/mole
Molar mass of PbO = 223 g/mole
First we have to calculate the moles of Pb.
Now we have to calculate the moles of
The balanced chemical reaction is,
From the reaction, we conclude that
As, 2 mole of react to give 2 mole of
So, 2.18 mole of react to give 2.18 mole of
Now we have to calculate the mass of
Theoretical yield of = 486.1 g
Experimental yield of = 367.5 g
Now we have to calculate the percent yield of the reaction.
Therefore, the percent yield of the reaction is, 75.6 %
First of all, as you seen the gases are noble which means that will not react with each other and in this case each gas create individual pressure.
P= total pressure
P = pressure of neon
P = pressure of argon
P = pressure of helium {which is required}
P = P
+ P
+ P
1.25 = 0.68 + 0.35 + P
P = 1.25 - [0.68 + 0.35] = 0.22 atm
