Answer is: 12,6% (1/8) <span>percentage of the sample will remain.
</span>c₀ - initial amount of C-14.<span>
c - amount of C-14 remaining
at time.
t = 5700</span> y.<span>
First calculate the radioactive decay rate constant λ:
λ = 0,693 ÷ t = 0,693 ÷ 5700</span> y = 0,000121 1/y = 1,21·10⁻⁴ y.
c = c₀·e∧-λ·t.
c = 2000 · e∧-(0,000121 1/y · 17100 y).
c = 252 g.
ω = 252 g ÷ 2000 g = 0,126 = 12,6%.

The compound calcium nitrate consists of a total of nine atoms<span>, including </span>one atom <span>of calcium, two of nitrogen and six of oxygen.</span>
In an aqueous solution that has not reached the saturation, the ions do not bond to create mineral crystals the motion of the ions that are dissolved would keep them from bonding. The ions creates temporary bonds to the partial charge present in the water molecules which will not allow for the ions to form a compound.
