Question

If 50 grams of water are saturated at 90°C with potassium nitrate and then cooled to 40°C, how much will precipitate?

Answer 1

43.1gramms

Step-by-step explanation:

change the temperatures to kelvin

90--363

40--313

50grams of water are saturated at 90 degree celcius.

then,

50___363

x_____313

then cross multiply

363x=15650

divide both sides by 363

x=43.1gramms
