What mass of silver oxide, ag2o is required to produce 25.0 g of silver sulfadiazine, agc10h9n4so2, from the reaction of silver oxide and sulfadiazine?
2c10h10n4so2 + ag2o ? 2agc10h9n4so2 + h2o

8.1107 g

Explanation:

The given reaction:

Given that:

Mass of silver sulfadiazine = 25.0 g

Molar mass of silver sulfadiazine = 357.14 g/mol

The formula for the calculation of moles is shown below:

Thus,

From the reaction,

2 moles of silver sulfadiazine are formed from 1 mole of silver oxide

So,

1 mole of silver sulfadiazine are formed from 1/2 mole of silver oxide

0.07 mole of silver sulfadiazine are formed from 1/2*0.07 mole of silver oxide

Moles of silver oxide = 0.035 moles

Molar mass  of silver oxide = 231.735 g/mol

Mass = Moles * Molar mass = 0.035 moles * 231.735 g/mol = 8.1107 g

the dissolution of polymer can be thermodynamically described in 2 steps.
