What is the volume of 2.3 mol sample of Fluorine at STP?

An aqueous solution of glucose is prepared by dissolving solid glucose in pure water at 300 K. Through this solution, 20 L of dry nitrogen gas is passed at 1.0 atm and 300 K. As a result, the solution...

how do you get started, with what formula?

Formula for Barium oxide?

Does increasing or decreasing volume change the moles in a solution, or does that just affect the concentration? If I have 0.035711 moles in 100mL and I'm asked how many moles in 5mL...
