If you want 44.8 Liters of NH3 to be produced from the reaction below, then how many grams of N2 gas should you start with? There is excess hydrogen (H2) gas provided for the reaction.
N2 + 3H2  2NH3
Density of NH3 gas at STP is --- 0.761 g / L
Molar mass of NH3 is --- 17.04 g / mol
Molar mass of N2 is --- 28.02 g / mol

You mix the pks of succinic acid are 4.21 and 5.64. how many gramsa graduate student at sdsu wants to measure the activity of a particular enzyme at ph 4.0. to buffer her reaction, she will use a buffer system based on one of the acids listed below, which acid is most appropriate for the experiment? of monosodium succinate (fw = 140 g/mol) and disodium succinate (fw = 162 g/mol) must be added to 1 l of water to produce a solution with a ph 5.28 and a total solute concentration of 100 mm? (assume the total volume remains 1 liter, answer in grams monosodium succinate, grams disodium succinate, respectively.) volumes of 0.05 m nah2po4 and 0.05 m na2hpo4 (pk's for phosphoric acid are 2.15, 6.82 and 12.38). which of the following best describes the resulting solution?
