How do you calculate solubility percentage? For example if a out 5 grams of sugar in 50 ml of water, with the temperature of water being 20 degrees.
The solubility of CO2 in water at 25°C and 1 atm is 0.034 mol/L. What is its solubility under atmospheric conditions? (The partial pressure of CO2 in air is 0.0003 atm.) Assume that CO2 obeys Henry's law.
What volume of 0.25 M HCl solutions must be diluted to prepare 1.00 LK of 0.040 M HCl?
Properties of subatomic particles - Fill in the missing relative masses and relative charges for each of the subatomic particles
