A geochemist in the field takes a 25.0 L sample of water from a rock pool lined with crystals of a certain mineral compound X . He notes the temperature of the pool, 26 C, and caps the sample carefully. Back in the lab, the geochemist filters the sample and then evaporates all the water under vacuum. Crystals of X are left behind. The researcher washes, dries and weighs the crystals. They weigh 2.3 g . how is this question different from the last question in the video?
For your question sample of pool water is taken. But in the question in video sample of crystal X was taken and was dissolved in distilled water. Pool water is a saturated solution since there are more crystal X present.
Wish you the best on your YT channel though. Probably will never see you again. I'm a fourth-year chemistry student, and this content probably wont be of much help in the future, but I wish you the best. Cheers, Tyler
Just what I was looking for. Thank you!
In the last problem, it states that some of Crystal X is left behind so that means that its possible to calculate the solubility, no?
I was wondering the same thing
The crystal left behind is what dissolved but the solution needs to be saturated in order to calculate the solubility.

How did you know that the first problem was a saturated solution?
"Only a little X has dissolved"
YT algorithm is weird. Just got suggested this video with no views. I love Math/science content, but I'm just pointing out this is weird.
