For reaction 3A + 2B → A3B2 ΔrH°= 83.6 kJ/(mol rxn) "A" molar mass = 22 g/mol; "B" molar mass= 105.7 g/mol what is the enthalpy change in kJ if 50 g of A react with 50 g of B?
Added by Julianna V.
Step 1
- Given the molar mass of A is 22 g/mol. - Mass of A = 50 g. - Number of moles of A = mass / molar mass = 50 g / 22 g/mol = 2.27 moles. Show more…
