<u>Answer:</u> The theoretical yield of the lithium chlorate is 1054.67 grams
<u>Explanation:</u>
To calculate the mass for given number of moles, we use the equation:
![\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20moles%7D%3D%5Cfrac%7B%5Ctext%7BGiven%20mass%7D%7D%7B%5Ctext%7BMolar%20mass%7D%7D)
Actual moles of lithium chlorate = 9.45 moles
Molar mass of lithium chlorate = 90.4 g/mol
Putting values in above equation, we get:
![9.45mol=\frac{\text{Actual yield of lithium chlorate}}{90.4g/mol}\\\\\text{Actual yield of lithium chlorate}=(9.45mol\times 90.4g/mol)=854.28g](https://tex.z-dn.net/?f=9.45mol%3D%5Cfrac%7B%5Ctext%7BActual%20yield%20of%20lithium%20chlorate%7D%7D%7B90.4g%2Fmol%7D%5C%5C%5C%5C%5Ctext%7BActual%20yield%20of%20lithium%20chlorate%7D%3D%289.45mol%5Ctimes%2090.4g%2Fmol%29%3D854.28g)
To calculate the theoretical yield of lithium chlorate, we use the equation:
![\%\text{ yield}=\frac{\text{Actual yield}}{\text{Theoretical yield}}\times 100](https://tex.z-dn.net/?f=%5C%25%5Ctext%7B%20yield%7D%3D%5Cfrac%7B%5Ctext%7BActual%20yield%7D%7D%7B%5Ctext%7BTheoretical%20yield%7D%7D%5Ctimes%20100)
Actual yield of lithium chlorate = 854.28 g
Percentage yield of lithium chlorate = 81.0 %
Putting values in above equation, we get:
![81=\frac{854.28g}{\text{Theoretical yield of lithium chlorate}}\times 100\\\\\text{Theoretical yield of lithium chlorate}=\frac{854.28\times 100}{81}=1054.67g](https://tex.z-dn.net/?f=81%3D%5Cfrac%7B854.28g%7D%7B%5Ctext%7BTheoretical%20yield%20of%20lithium%20chlorate%7D%7D%5Ctimes%20100%5C%5C%5C%5C%5Ctext%7BTheoretical%20yield%20of%20lithium%20chlorate%7D%3D%5Cfrac%7B854.28%5Ctimes%20100%7D%7B81%7D%3D1054.67g)
Hence, the theoretical yield of the lithium chlorate is 1054.67 grams
