PM = 1 g/mol×2 + 32 g/mol×1 + 16 g/mol×3
= 2 g/mol + 32 g/mol + 48 g/mol
PM = 82 g/mol
M = gramos soluto
PM × Litros
M = 90 g ⇒ 90 g
82g/mol×1,2 L 98,4g/mol.L
M = 0,915 mol/L
Cuál es el por ciento en volumen de 50 ml de HCl disueltos es 750 ml de agua?
%volumen = volumen soluto × 100
volumen solucion
volumen solucion = soluto + solvente
= 50 ml + 750 ml
= 800 ml
% vol = 50 ml × 100
800 ml
% volumen = 6,25
porfa, calificame...gracias
