Flask Q (volume = 1.00 x 103 cm3 ) is filled with ammonia (NH3) at 102 kPa and 300 K. Calculate the mass of ammonia in flask Q. (Gas constant R = 8.31 J K−1 mol−1 )

n = PV/RT 102 000 ×(1.00 × 10−3) / 8.31 × 300 = 𝑛 n= (4.091456077x10-2) Mass = n x 17 = 0.696g (3 sig figs only)

Use the following data to explain why NaCl is soluble in water: ∆H = +31 kJmol-1, S(Na+(aq)) = 320.9 JK-1mol-1, S(Cl-(aq)) = 56.5 JK-1mol-1, S(NaCl(s)) = 72.1 JK-1mol-1 Are there any temperatures at which you would not expect NaCl to dissolve?
