Answer:
1813.74g
Explanation:
Given parameters:
Number of moles of radon = 8.17moles
Unknown:
Mass of radon = ?
Solution:
To solve this problem, we use the expression below:
Number of moles =
Molar mass of radon = 222g/mol
Now insert the parameters and solve;
Mass of radon = Number of moles x molar mass
= 8.17 x 222
= 1813.74g
Answer:
Theoretical yield = 13.7 g
% yield =76 %
Explanation:
For
Mass of = 4.07 g
Molar mass of = 101.96 g/mol
The formula for the calculation of moles is shown below:
Thus,
According to the reaction:
1 mole of on reaction produces 1 mole of
So,
0.0399 mole of on reaction produces 0.0399 mole of
Moles of obtained = 0.0399 mole
Molar mass of = 342.2 g/mol
The formula for the calculation of moles is shown below:
Thus,
<u>Theoretical yield = 13.7 g</u>
The expression for the calculation of the percentage yield for a chemical reaction is shown below as:-
Given , Values from the question:-
Theoretical yield = 13.7 g
Experimental yield = 10.4 g
Applying the values in the above expression as:-
<u>% yield =76 %</u>
