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?

Step one write the chemical equation for reaction

= Ag2O + 2 (C10H10N4SO2) - - - > 2 (AgC10H9N4SO2)

The reacting ratio of Ag2O to AgC10H9N4SO2 is 1:2 from the reaction above

step 2; find the number of moles of AgC10H9N4SO2

that is mass/molar mass

The molar mass of AgC10H9N4SO2 = 107.86 + (12 x10) + (1 x 9) + (4 x 14) + 32 + (16 x2) = 356.86g/mol

moles is therefore = 25g/356.86g/mol = 0.07moles

by use of mole ratio the moles of Ag2O = 0.0702=0.035moles

mass = moles x molar mass

the molar mass of Ag2O=231.72 g/mol

mass is therefore = 231.72g/mol x 0.035moles = 8.11grams
