Hello!
Begin by converting molecules to moles using Avogadro's number:
Simplify:
Therefore, there are moles in molecules of .
Answer:
True
Explanation:
Specific volume is defined as volume occupied by unit mass. Its unit is meter cube/kg. Thus, specific volume can also be defined as volume occupied by 1 kg of mass.
It is also inverse of density as density is ratio of mass upon volume.
It is an intrinsic value as it does depend upon the amount of the substance.
Therefore, the given statement is true.
Answer:
4.002602
Explanation:
the average that reflects the typical ratio of natural abundances of its isotopes.
6.00x10^9 Co atoms / 6.022x10^23 Co atoms = 9.96x10^-15 moles of Co
