Question

Сколько грамм хлорбензола требуется,чтобы взять 78г фенола, если производственная потеря составляет 50%

Answer 1

M=78*50/100=39г надо взять хлорбензола без примесей

Answer 2

Calculating the Amount of Chlorobenzene Needed to Obtain 78g of Phenol with a 50% Production Loss

To calculate the amount of chlorobenzene needed to obtain 78g of phenol, considering a 50% production loss, we can use the following formula:

Amount of Chlorobenzene = Amount of Phenol / (1 - Production Loss)

Substituting the given values:

Amount of Chlorobenzene = 78g / (1 - 0.50)

Amount of Chlorobenzene = 78g / 0.50

Amount of Chlorobenzene = 156g

So, 156 grams of chlorobenzene are required to obtain 78g of phenol, considering a 50% production loss.
