The molar mass of Ca(NO₃)2 is 164 g/mol
<u><em> Explanation</em></u>
Ca(NO₃)2 is made up of Ca , N and O elements
Therefore the molar mass of Ca(NO₃)2 = molar mass of Ca + molar mass of N +molar mass of O
from periodic table the molar mass of Ca is 40 g/mol
for N = 14 g/ mol
for O = 16 g/mol. since they are 3 atoms of O in Ca(NO₃)2 the molar mass = 16 x3 = 48 g/mol
The molar mass of Ca(NO₃)2 = 40 g/mo + [(14 g/mol + 48 g/mol) 2] =164g/mol
El ejercicio completo con las formulas es el siguiente:
cuál de las siguientes fórmulas no cumple con la tetravalencia del átomo de carbono.
a. CH3-CH2-CH2-OH
b. CH3-CH=CH2
c. CH3-CH2=CH2
d. CH3-CH2-CH3
Answer:
La respuesta correcta es la opción C
Explanation:
En la formula C, podemos ver claramente que no se cumple con la tetravalencia del carbono pues al sumar el total de las valencias del carbono nos da 5
CH3 - CH2 = CH2 = Total de valencias del carbono 5
1 + 2+ 2 = 5
Para que la formula sea correcta debe eliminarse un hidrogeno quedando la formula de la siguiente manera:
CH3 - CH = CH2
1 + 1 + 2 = 4
People save fuel and decrease travel times because the coriolis effect causes winds so the planes will receive a push from the wind
