Sodium Hydroxide NaOH - PubChem
WitrynaAnswer 1: The relative atomic mass of sodium is not 23 amu (amu = atomic mass unit), it is 23 with no units (as is suggested by the word "relative") . The relative atomic mass is the ratio of the average mass of an atom of an element (given in amu) to 1 amu. http://scienceline.ucsb.edu/getkey.php?key=6288 hong kong 3 restaurant menu

Witryna(a) the ion with a 3+ charge, 28 electrons, and a mass number of 71 (b) the ion with 36 electrons, 35 protons, and 45 neutrons (c) the ion with 86 electrons, 142 neutrons, and a 4+ charge (d) the ion with a 2+ charge, atomic number 38, and mass number 87 13. Open the Build an Atom simulation and click on the Atom icon. Witryna7 kwi 2024 · The atomic mass of sodium is 22.9898 g / m o l . The atomic mass of oxygen is 15.999 g / m o l. The atomic mass of Hydrogen is 1.00794 g / m o l . On adding every one of the molar masses of what makes sodium hydroxide. 22.989 g / m o l + 15.999 g / m o l + 1.008 g / m o l = 39.996 g / m o l . Note: We need to know that N … WitrynaThe balanced equation is: NaOH (aq) + HCl (aq) → NaCl (aq) + H2O (l) So the mole ratio NaOH:HCl is 1:1 Therefore 0.00250 mol of NaOH reacts with 0.00250 mol of HCl Step 3: Calculate the... hong kong academy debenture
