I have 370 grams of paraformaldeyhde and i want to make a 37% formaldeyhde solution out of this amount ?.
1 Answer
Heat the paraformaldehyde with 990 mL water.
Explanation:
Paraformaldehyde is a polymer of formaldehyde with the formula
You can depolymerize paraformaldehyde and form a formaldehyde solution by heating it with water.
Assume that
Then
Calculate the mass of formaldehyde
In other words, depolymerization of a given mass of paraformaldehyde produces approximately the same mass of formaldehyde.
Calculate the mass of water required
Thus, you heat the paraformaldehyde with 990 mL water.
