Question

Calculate the heat for the formation of 350 g of ammonium bromide as follows:
NH3 + HBr → NH4Br + 188 kJ.

Answer 1

Can someone also explain and show the steps on how to solve this stoichiometry problem?

Answer 2

pretty sure, Hf =188 kJ/mol

so find how many moles there are in 350 g of NH4Br

then multiply it by the enthalpy of formation.
