Explanation:

hope it's help u

Answer 2

Answer:

Molar mass NaOH = 40 g/mol

• 4 g NaOH = 0.1 mol

• 1 mol atoms = 6.022*10^23 atoms

• You have 0.1 mol Na atoms . That is 6.022*10^22 Na atoms, Atomic number Na = 11

• Each atom has 11 protons . Total protons = 6.022*10^22 * 11 = 6.62*10^23 protons

• You have 0.1 mol O atoms . That is 6.022*10^22 O atoms, Atomic number O= 8

• Each atom has 8 protons . Total protons = 6.022*10^22 * 8 = 4.82 *10^23 protons

• You have 0.1 mol H atoms . That is 6.022*10^22 H atoms, Atomic number H = 1

• Each atom has 1 protons . Total protons = 6.022*10^22 * 1 = 6.02*10^22 protons

• Total number of protons = 6.62*10^23 +4.82 *10^23 +6.02*10^22 protons

• Total protons = 1.20*10^24 protons
