When you calculate the molarity and molality of the EDTA solution are the values very similar or not? Explain if this is what you might expect for a dilute aqueous solution with a density very close to 1.0 g/mL.
The volume of a 24.0g sample of methane gas is 22.8L at 40.0*C and 4.00atm. What will it's volume be at 68.0*C and 4.00atm.
If someone can go in depth into finding the Ka to this and then guiding me through the rest of the steps, I'd be eternally grateful
Write out the additional equations you would need to consider. d. Confirm that the number of equations is equal to the number of unknowns.
What is the percent hydrogen (H) by weight of a solution containing 53.5 mL of CH3COCH3? The density of acetone is 0.788 g/mL.
A solution is made my mixing equal masses of methanol, CH4O and ethanol, C2H6O. Determine the mole fraction of each component to at least three significant figures.
An electrochemical cell is constructed with a zinc metal anode in contact with a 0.052 M solution of zinc(II) nitrate and a silver cathode in contact with a 0.0042 M solution of silver(I) nitrate. What is the emf of this cell at 5°C
