How many grams of NH4Cl are needed to make a saturated solution in 100 g of water at 50°C? (Record the NUMBER only, NO units)

50 grams NH₄Cl per 100 grams water.    

Explanation:

See attached => Using the Salt Saturation Curve, trace from x-axis at 50°C up to NH₄Cl curve, then horizontally to the y-axis to value needed, 50 grams NH₄Cl per 100 grams water.    

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
