Food rotting is a CHEMICAL CHANGE
A strong electrolyte like MgCl2 dissociates completely as per the following reaction:
As you can see, from 1 molecule of MgCl2 produces 3 ions on dissociation.
So, 1 mole of MgCl2 produces 3 moles of ions.
Now, Moles of MgCl2 = Volume x Molarity
= 0.04 x 0.345 [Change volume to Litres]
= 0.0138 moles
Now, total moles of ions = 0.0138 x 3 = 0.0414
<span>To find the percent yield, we first need to write this out as an equation:
3A + 2B --> C + 6D. The moles of C equals 1/3 times the moles of A. Therefore, the moles of C equals 4/3.
The theoretical yield equals = moles x molar mass of C.
(4/3) x (310.2) = 413.6g
The percent yield equals actual yield/theoretical yield x 100%.
382.5g/413.6g x 100% = 92.48%</span>
