0.250 L * 0.150 mol/L = 0.0375 mol.
0.0375 mol * 92.1 g/mol = 3.45 g.
1000 mL * 1.26 g/mol = 1260 g.
3.45 / 1260 * 1000 mL = 2.74 mL.
0.250 L X 0.150 mol/L = 0.0375 mol glycerol
0.0375 mol X 92.1 g/mol = 3.45 g glycerol
3.45 g / 1.26 g/mL = 2.74 mL glycerol
Si quiere, glicerol = G y la solucion = S.
250mLS x 0.150molG/1000mLS x 92.1gG/1molG x 1.00mLG/1.26gG = 2.74g glicerol
