For reaction 3A + 2B ? A3B2 ?rH°= 3,786.3 kJ/(mol rxn) "A" molar mass = 154.5 g/mol; "B" molar mass= 36.7 g/mol what is the enthalpy change in kJ if 50 g of A react with 50 g of B?

          For reaction 3A + 2B ? A3B2
?rH°= 3,786.3
kJ/(mol rxn)
"A" molar mass = 154.5 g/mol; "B" molar mass= 36.7 g/mol
what is the enthalpy change in kJ if 50 g of A react with 50 g of B?

Step 1

Given: Mass of A = 50 g Molar mass of A = 154.5 g/mol Mass of B = 50 g Molar mass of B = 36.7 g/mol Moles of A = 50 g / 154.5 g/mol = 0.324 mol Moles of B = 50 g / 36.7 g/mol = 1.36 mol Show more…
