Question

49,04 g de H25O4 en 250 ml de solución

Answer 1

Respuesta:

M = 2 molar

Explicación:

49,04 g de H25O4 en 250 ml de solución

Mm H2SO4: 98 g/mol

fórmula:

M = moles soluto (n)

                V(L)

1. Calcular volumen en litros

V = 250 / 1000

V = 0.250 L

2. Calcular moles de soluto

n = masa/Mm

n = 49.04 g / 98 g/mol

n = 0.500 moles de soluto

3. calcular molaridad

M = 0.500 moles

         0.250 L

M = 2 molar

M = masa_

Mm x V(L)

M = ____49.04 g_____

       98 g/mol x 0.250 L

M = 2 molar
