An ionic molecular solid AX has a molecular weight 250 g/mol is face centered cubic with regard to the anions, X, which have a radius of 300 pm. The cations, A+, have radius 200 pm and are found octahedral interstitial spaces. The edge of each unit cell is as long as the diameter of 1 cation and 1 anion. When 25 grams of AX (as described above) is dissolved into 500 grams of water at 293.15 K 41.36 kJ of...

Trying this again... I need how much of this liquid will make the solution add up to be 1L, so the answer can't be more than 1L. Glacial acetic acid is 99.5% acetic acid (f.w. 60.052) by weight and has a density of 1.05g/mL. Calculate the volume of glacial acetic acid needed to make 1L of the 0.100M pH 5.000 buffer.
