A reaction was conducted between barium nitrate and sodium phosphate. 3 Ba (NO3) 2 + 2 Na3PO4 → 6 NaNO3 + Ba3 (PO4) 2 What is the percent yield if 0.3 mol Ba (NO3) 2 and 0.25 mol Na3PO4 react to produce 0.095 mol Ba3 (PO4) 2? To prepare an approximate 1 molar solution of sodium hydroxide - dissolve 40 gm (1 mole) of NaOH (sodium hydroxide) in 1 L of distilled water. It is more convenient to prepare an approximate NaOH solution at approximately 1 M strength, as 40 g of NaOH + H 2 SO 4 → H 2 O + Na 2 SO 4 .
