What are the equations you use to figure out these mole problems?

1) How many moles of solute are in 30 mL of a 2.5 M solution?





2) The carbon dioxide in a sealed popo has a solubility of 4.5 g/L at a pressure of 2.5 atm. What is the new solubility when the pop is opened and the pressure is at 2 atm?





You do not have to slove these for me.. i can do it myself, i just need the equations. thanksWhat are the equations you use to figure out these mole problems?
molarity = moles / liter just solve for moles = M x V





there are solubility curves for all gases


with the decreased pressure, there will be less gas soluble in solution, it is inverse to that of solids and liquids.





what happens when the soda increases in temperature. the CO2 solubility also decreases. this website may help
