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.​

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins. co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)
