Question

1 litro de solucion de NaOH 1M? Ayuda :(

Answer 1

Respuesta:

M = moles soluto

     litros solucion

moles = M × litros

moles = 1 mol/l × 1 l

moles = 1 mol

moles = gramos /PM

gramos = mol × PM

gramos = 1 mol × 40 g/mol

gramos = 40 g

PM = 23 g/mol ×1 + 16 g/mol ×1 + 1 g/mol ×1

PM = 23 g/mol + 16 g/mol + 1 g/mol

PM NaOH = 40 g/mol
