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

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
