What is the maximum percent recovery if 5.0 g of acetanilide is recrystallized from 100 mL of water? VOs;q67~=fnKk?aB+a$L\LjOvax[? WebMaximum theoretical percent recovery = (mass recovered / original mass dissolved) x 100% Maximum theoretical percent recovery = (0.949 / 1.00) 100% = 94.9 % Therefore, the maximum theoretical percent recovery from the recrystallization of 1.00 g of benzoic acid from 15 mL of water = 94.9% Advertisement Advertisement document.getElementById ( beforeSubmit: function(){
What is the maximum percent recovery that can be achieved for the recrystallization of acetanilide from ethanol? a. Shouldn't the lattice favor the dominant compound? Then you must obtain, $$m^\mathrm{c}=m^\mathrm{t}\left(\frac{\frac{m_A^\mathrm{i}}{m^\mathrm{t}}-x_A^\mathrm{c}}{x_A^\mathrm{liq}-x_A^\mathrm{c}}\right)$$. The solubility for both is given at two different temperatures. } else {
function(){ What is the percent recovery in the first crop?
} Doing the balanced equations about the mass of $A$ in each phases you have : $$\begin{cases} Notice that $\frac{m_A^\mathrm{i}}{m^\mathrm{t}}=x_{A,\mathrm{i}}^\mathrm{liq}$ which is the mass-fraction at the begining in the liquid and $x_A^\mathrm{liq}$ is the mass-fraction in the liquid at the end. Since most reactions do not go to completion or afford byproducts, the crude product is more or less contaminated with other compounds.
