Because 1,2-diaminoethane is base, this compound gain protons from acid (in this example hydrochloric acid) and becaume ionic compound with positive charge (cation).
1,2-diaminoethane is organic compound and hydrochloric acid is inorganic compound.<span>
Balance chemical reaction:
</span>H₂NCH₂CH₂NH₂(aq) + 2HCl(aq) → ⁺H₃NCH₂CH₂NH₃⁺(aq) + 2Cl⁻(aq).
To convert from grams to moles, you must divide the given mass by the molecular weight. If this is so, then:
Water ≈ 18.02 grams/mol.
85.0 g/ 18.02 g/mol ≈ 4.72 moles
