The solubility of acetanilide is 18.5 g in 100 ml of methanol at 0 °c, and 59.2 g in 100 ml of methanol at 60 °c. what is the maximum percent recovery that can be achieved for the recrystallization of acetanilide from methanol?

Percent recovery is an indication of how much of active ingredient one is able to recover after purification method.

The formula for percent recovery is:

Substituting the values in the above formula:

%

Hence, the maximum percent recovery that can be achieved for the recrystallization of acetanilide from methanol is %.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
