The M stands for molar, so it would be 5.0 molar. is that what you need?
Methanol(CH3OH) is a nonelectrolyte as it is not readily ionized when melted and dissolved, and a poor conductor of electricity when it is in solution.
Nanelectrolyte Contains covalent bonds and typically nonpolar molecules. Methanol doesn't dissolve in water, as the H of the alcohol functional group is not acidic enough so we can't easily separate it from the molecule.
The activity of the sample is:
R₀ = 4.5 x 10⁻⁶ Ci (3.70 x 10¹⁰ decays/s / 1 Ci)
= 166500 decays / s
The number of nuclei is:
N₀ = (166500 decays/s) / (5730 yr * 3.154 x 10⁷s /1yr) = 9.2 x 10⁻⁷
The mass of a ₆C¹⁴ source is:
m = N₀m₀ = (9.2 x 10⁻⁷) * (2.34 x 10⁻²⁶) = 2.16 x 10⁻³² kg
Answer:
An isotope is one of two or more forms of the same chemical element. Different isotopes of an element have the same number of protons in the nucleus, giving them the same atomic number, but a different number of neutrons giving each elemental isotope a different atomic weight.
