Molality= moles NaCl/ Kg H2O
250 g (1 Kg/ 1000 grams)= 0.250 Kg
Molality= 0.611 moles/ 0.250 Kg= 2.44 molal
Answer:
AlBr3
Explanation:
Aluminum has three electrons on its valence shell. The Lewis model deals with combination of electrons on the valence shells of atoms to form compounds. Bromine has seven electrons on the valence shell of each bromine atom.
Three bromine atoms could combine with one aluminium atom to form aluminium bromide in which each bromine atom now has eight electrons in their valence shells according to the octet rule. Aluminium however will only have six electrons on its valence shell.
