Explanation:
Respuesta: La masa atómica del carbono (C) es 12 g/mol; para el oxígeno (O) es de 16 g/mol. Esto significa que 6.022 x 1023 átomos de carbono pesan 12 gramos. Según esto, el peso molecular del CO2 es: 12 g/mol [C] + 2 x 16 g/mol [O2] = 44 g/mol

Hydrogen is easily the most abundant element in the universe.
It is found in the Sun and most of the Stars, and the planet Jupiter is composed mostly of Hydrogen.
I hope this helps...
Answer: Option (B) is the correct answer.
Explanation:
Molar mass is defined as the sum of masses of all the atoms present in a compound.
For example, atomic mass of barium is 137.32 g/mol and atomic mass of bromine is 79.90 g/mol.
Therefore, molar mass of
will be as follows.
Molar mass = atomic mass of Ba +
= 137.32 g/mol + 
= 297.12 g/mol
Hence, we can conclude that molar mass of [tex]BaBr_{2}[tex] is 297.12 g/mol.
