1.-ACIDO ACETILSALICILICO (VINAGRE)
REACTIVO: 10ml HC2H3O2 2M DENSIDAD: 1.049 g/ml
10 ml = 0.01 L M=n/V n=MV n= (2M) (0.01L) = 0.02 mol
P.M. 4H (1.0079)n=W/P.M. W= (n) P.M. W= (0.02 Mol) (60.0516 g/mol =1.201032 g
2C (12.011) densidad=W/V V=W/densidad
2O(15.999) V= 1.201032 g/ 1.049 g/ml = 1.14493041 ml
60.0516 g/mol

2.-ACIDO CLORHIDRICO
REACTIVO: 25ml HCl 12MDENSIDAD: 1.18 g/ml
25 ml = 0.025 L n=MV n= (12M)(0.025)= 0.03 mol
P.M. = 36.4609 g/mol W=n (P.M.) W= (0.3)(36.4609)= 10.93827 g
V=W/DENSIDAD V= 10.93827/1.18=9.269720339 ml

3.-CLORURO DE BARIO
REACTIVO: 10 ml BaCl2 1M
10 ml = 0.01L n=(1M)(0.01) = 0.01 mol
P.M. 172.793 W=(n)(P.M.) W= (0.01)(172.793) = 1.72793 g

4.-ACIDO NITRICOREACTIVO: 10ml HNO2 15M DENSIDAD: 1.5129 g/mol
10ml=0.01L n= (15M)(0.01)= 0.15mol
P.M.= 63.0109 g/mol W=(n)(P.M.) W=(0.15mol)(63.0109) = 9.451635
V= W/DENSIDAD V=9.451635/1.5129 g/ml V=6.2473 ml

5.-HIDROXIDO DE AMONIO
REACTIVO: 25ml NH4OH 15M DESNSIDAD:1.5 g/mol
25ml=0.025L n=(0.025)(15) =0.375 mol
P.M.=35.0445 g/mol W=(0.375)(35.0445) = 13.1416875g
V=W/DENSIDAD V=13.1416875/1.5= 8.761125 ml

6.-HIDROXIDO DE SODIO
REACTIVO: 25 ml NaOH 10M n=(0.025)(10) =0.25 mol
P. M.=39.9959 g/mol w=(39.9959)(0.25)= 9.9998975 g7.-CARBONATO DE AMONIO
REACTIVO: 10ml (NH4)2CO3 3M n=0.01(3M)= 0.03mol
P.M. 96.0832 g/mol W=(0.03)(96.0832)= 2.882496 g

8.-CLORURO FERRICO
REACTIVO: 10ml FeCl3 1%V DENSIDAD: 2.8g/mol
