As per the statement stated in the problem "weighed all the raccoons that were trapped in suburban neighborhoods" clearly shows the confirmation of the same.
Answer: Yes he is successfull because he has released many books.
Explanation:
Molality is simply defined as the number of moles of
solute over the mass of the solvent.
In this case the solute is NaCl and the solvent is water,
therefore:
moles solute = 0.630g/ 58.44 g/mol = 0.0108 mol
So the molality is:
m = 0.0108 mol / (0.525 kg)
<span>m = 0.0205 molal</span>
It depends on weather or not the chemicals used can cause problems if not and it's a safe substance than yes they should pour it down the drain
