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)

Answer:
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.
