Question

2. La masa molar del NaHCO3 es: Datos: M Na = 23 g/mol , M H = 1 g/mol , M C = 12 g/mol y M O =16 g/mol
52 g/mol
84 g/mol
50 g/mol
74 g/mol
83 g/mol

Answer 1

M(NaHCO3) = M(Na) + M(H) + M(C) + 3M(O)

M(NaHCO3) = 23 g/mol + 1 g/mol + 12 g/mol + 3(16 g/mol)

M(NaHCO3) = 36 g/mol + 48 g/mol

M(NaHCO3) = 84 g/mol
