You are given a 76.0% solution of sulfuric acid, H2SO4. What is the molality of this solution? The density of the H2SO4 solution is 1.278 g/mL.
25.0 cm3 of a saturated solution of Ca(OH)2 required 21.0 cm3 of 0.0500 mol dm-3 HCl for complete neutralisation. Calculate the [OH-(aq)] and the [Ca2+(aq)] in the saturated solution.
How many moles of nitrogen, N, are in 65.0 g of nitrous oxide,N2O ? Express your answer with the appropriate units.
Suppose that the atomic mass unit (amu) had been defined as one-eighth of the average mass of an atom of sodium instead of one-twelfth of the mass of an atom of carbon-12. What would the average atomic mass of magnesium be on this new scale
A sample of gas weighs 3.718g and has a volume of 1.4L at .845 torr and 26.0 C. What is its molar mass?
A precipitate of calcium phosphate is in contact with 653.9 mL of water. How many grams of calcium ion are present in the solution
The solubility product constant (Ksp) for the dissolution of CaF2 as represented by the chemical equation is 3.4 x 10-11. CaF2 (s) Ca2+ (aq) + 2 F- (aq) Calculate the molarity (M) of Ca2+ in a saturated solution of CaF2
Calculate the concentrations of all species in a 1.73 M Na2SO3 (sodium sulfite) solution. The ionization constants for sulfurous acid are Ka1 = 1.4× 10-2 and Ka2 = 6.3× 10-8.
A 9-mm Xian short-barrel experimental pistol is fired and the reacting, exploding gases push the bullet down the barrel of the gun. The pressure is recorded as the bullet accelerates to the exit.
An incompressible fluid (p(ro)= const) is contained in an insulated cylinder fitted with a frictionless piston. Can energy as work be transferred to the fluid?
Hydrogen gas (2g) is aded to a 10L rigid vessel at 298K containing 4g of He gas. What is the new pressure within the vessel
You are checking the accuracy of a volumetric flask marked 10.00 mL. You measure the volume of water contained in the flask by measuring the mass of the empty flask
explain why one would be higher than the other? I'm confused as to the theory of this lab and need to know exactly why...Thanks! I have this lab next week and can't unnderstand what the concept is.
