Carbon -13 has 7 neutrons and carbon -12 has six neutrons. Carbon -12 is the most common isotope of Carbon. Carbon -14 is radioactive and vary rare. The symbols for the isotopes of Carbon atoms shown here indicate they each have six protons but mass numbers of 14, 13, and 12. Hope this helps. :)
One mole of methane has a mass of 16 g
The formula for hydrogen-hydrogen is H-H
The number of mole of oxygen gas, O₂ in the cylinder given the data is 0.5 mole
<h3>Description of mole </h3>
The mole of a substance is related to it's mass and molar mass according to the following equation:
Mole = mass / molar mass
<h3>How to determine the mole of O₂</h3>
From the question given, the following data were obtained:
- Mass of O₂ = 16 g g
- Molar mass of O₂ = 32 g/mol
- Mole of O₂ =?
Mole = mass / molar mass
Mole of O₂ = 16 / 32
Mole of O₂ = 0.5 mole
