Determinent masa molar del oxigeno
libre (0) Para ello
Consulten en su tabla periodica la masa atomica del oxigeno y anotenia con su unidad
anterior actividad
c) Expresen esta cantidad en gramos para obtener la masa molar
¿Cuantas moléculas hay en un mol de O,?
9
e) Consulta en la tabla penodica las masas atomicas del orogeno y del oxigeno, respectivamente. H
1) 6) Determina la masa molecular del agua (H,0)
g) Obten la masa molar del agua expresando su masa molecular on gramos
(Considera que 1 g de agua pura a 5°C y 1 stm de presión corresponde a 1
Un mol de H20 =
mi
h) Anota entonces cuántas moléculas de agua pura a 5 C hay en 18 ml
Por último, calcula cuantas moléculas de agua hay en una gota, si en cada mitro hay 20 gotas de
agua.​

Darla claims that the first periodic table developed by mendeleev was not completely accurate, so it is not useful at all. harmony argues that it establish the periodic table we use today, making it more credible. who is correct and why? darla is correct, because a model that has any mistakes should be thrown out. darla is correct, because a good model would not need to change. harmony is correct, because mendeleev’s model had all of the information correct in the first version. harmony is correct, because mendeleev’s model made predictions that came true.

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
