Isotopes of any given factor all incorporate the equal variety of protons, so they have the identical atomic wide variety (for example, the atomic wide variety of helium is usually 2). Isotopes of a given factor include exceptional numbers of neutrons, therefore, special isotopes have special mass numbers.
A solution is a mixture of two or more substances combined so that it is uniform, which means you cannot see the components. <span />
It's a thermodynamic quantity equal to the enthalpy minus the product of entropy and the absolute temperature
1 μL = 10^-6 L by definition
So...
82 μL = 82x10^-6 L = 8.2x10^-5 L
