I am not sure how these type of question formats be answered:
1. A chemistry student prepares an aqueous solution of a gas, with 0.3 g of the gas at ordinary condition. If the pressure is
doubled what will be the mass of the gas will be dissolved?
2. If the absolute temperature of a gas is increased six times and its pressure is
tripled, then the volume will?
3. If the absolute temperature of a gas is
quadrupled and its pressure is
halved, then the volume will?
these questions are popular and often used in standardized tests with
limited time and I know that there is a technique/trick on how to solve this kind of questions
fast, I just forgot how. Please send help
A photo of the solution will be also very much appreciated
