Mm Glucosa = 180 g/mol
% m/v = masa soluto x 100
``````````````````
v solución
V = 6 x 1000 = 6000 mL
calcular masa soluto
m soluto = 2 g/mL x 6000 mL
``````````````````````````````
100
m soluto = 120 g de glucosa
calcular moles
moles = 120 g glucosa x 1 mol glucosa
````````````````````
180 g glucosa
moles = 0.667 de glucosa
% m/v = masa soluto x 100
``````````````````
