So, I'm not sure Hank mentioned this or not, but for those of you who got super confused like I did, it turns out that the gas constant in the Ideal Gas Law changes when in a solution! That's why Hank's value for R is 0. 08206 in this equation and not 8. 3145. They also have different units; 0. 08206 L atm/mol K and 8. 3145 L kPa/mol K, I think it all depends on what unit of measurement you're using for Pressure? But I am not an expert, so if this is obvious I apologise, but it confused the hell outta me lol.

I haven't even finished the video and I'm so glad I found this. Revising from the textbook given from school was just boring and this has actually done such an amazing job at making me interested in the subject. And yes, the Freddie Mercury and David Bowie reference is why I'm commenting.

which is more soluble a 100mg tablet in 250ml water or a 1000mg tablet in 250ml of water? if possible an explanation would be appreciated.
