WebDec 14, 2015 · Take the sum of the molar masses of each element. molar mass of Na = 22.990 g/mol. molar mass of O = 15.999 g/mol. molar mass of H = 1.008 g/mol. The sum is 39.997 g/mol. This can be rounded to an even 40 g/mol. Answer link. WebThe Answer is 8 grams of NaOH. Some pre-requisite knowledge to solve the question are: Molar mass of NaOH = 40u Molarity = Mass of solute × 1000/ (Molar mass of solute × Volume of solution in mL). It is given that M=0.4 and V= 500mL. By putting the values in formula we get: 0.4=Mass of NaOH ×1000/ (40×500).
