Truong-Son N. May 13, 2016. The molecular molar mass consists of the atomic masses of each atom. Sodium hydroxide is NaOH. Thus, its molar mass involves: MNa = 22.989 g/mol. MO = 15.999 g/mol. MH = 1.0079 g/mol. So, its molar mass is 22.989 + 15.999 + 1.0079 = 39.996 g/mol to 5 sig figs.
Our expert help has broken down your problem into an easy-to-learn solution you can count on. Question: What mass of sodium hydroxide (NaOH, molar mass = 40.0 g.mol-1) is needed to make 100.0 mL of a 0.125 M NaOH solution? OA) 0.0500 g OB) 0.500 g OC) 3.13 g OD) 5.00 g. Here’s the best way to solve it.
The units of molar mass are grams per mole, or g/mol. Molar mass allows scientist to convert between moles and grams, or vice versa. Answer and Explanation: 1 The molar mass of sodium hydroxide equals 39.997 g/mol.
Question: 4. Calculate the expected concentration of the sodium hydroxide solution. The molar mass of NaOH is 39.997 g/mol. 5. Calculate and record the expected mass of benzoic acid required to react with 20.00 mL of a 0.100 M sodium hydroxide solution. Record the mass of benzoic acid using three significant digits to reference later.
