Question

la masa molar de la glucosa(c6h12o6) es 180g/ mol ¡cuandots mol de glucosa estan contenidos en 6 litros de una disolucion al 3% m/v? urgente

Answer 1

1. calcular masa soluto despejando de la fórmula

% m/v = masa soluto  x 100
              ````````````````` 
                   v solc.                                           

masa soluto = 3 g/L  X  6 L
                      ``````````````````
                              100

masa soluto = 0.18 g de glucosa

2. calcular moles

moles = 0.18 g glucosa  x  1 mol glucosa
                                          ````````````````````
                                            180 g glucosa

moles = 0.001 de glucosa
