How many grams of ammonium chloride (NH4Cl) would be required to make a saturated solution in 1000 grams of water at 50 degrees

Pavel [41]

Since,
1000 grams of water = 1000 mL of water
So,
At any of the given temperature:
1000 mL = 10 x 100 mL

moles of NH4Cl = 53.5/53.49
= 1.0 m
= 1.0 mol/Kg
Delta T = 2 x 1.86 x 1.0
= 3.72 c
= - 3.72 °C
