1)What is the empirical formula of a compound that is 14.49% C by mass and 85.51% Cl by mass?
2)What is the molar mass of a gas where 20.0L of the gas at 26oC and 1.14atm has a mass of 29.7g?
3)45.00 mL of an aqueous H2SO4 solution required 32.0 mL of 0.200 M KOH(aq) to neutralize it completely. The unbalanced equation for the reaction is:
KOH(aq) + H2SO4(aq) → K2SO4(aq) + H2O(l)
The molarity of the H2SO4 solution is therefore:
