Could someone help me out with these three questions.Thanks.
1) If 3.15kg of sulfur reacts w. oxygen according to theequation below, calculate the volume of SO2 gas (in mL) formed at30.5*C and 1.04 atm.
S(s) + O2(g) --> SO2(g)
2) An aqueous solution of barium hydroxide has a pH of 9.78 at25*C. Calculate the concentration of the base.
3) What is the original molarity of an aqueous solution ofammonia (NH3) whose pH is 11.22 at 25*C? (Kb for NH3 = 1.8 x10^-5).
