Methane is a thick substance not allowing it to fill the air and it is also a natural gas, so it would cause no harm.
To identify the amount of chloride ions present in 0.1 mol
of MgCl2, first know the amount of mols of Chloride. The answer is 0.2 mol
since you just need to multiply 0.1 to 2 because there are 2 chloride in the
compound. Then, multiply the mols to 6.02x10^23. The answer would be
1.204x10^23 chloride ions.
