How many grams of ammonium chloride (NH4Cl) would be required to make a saturated solution in 1000 grams of water at 50 degrees Celsius?
0 degrees Celsius - 90 g/100 mL
10 degrees Celsius - 70 g/100 mL
20 degree Celsius - 55 g/100 mL
30 degree Celsius - 45 g/100 mL
40 degrees Celsius - 35 g/100 mL
50 degrees Celsius - 29 g/100 mL
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
