Answer:
the specimen has 11460 years old
Explanation:
if the live sample has as initial amount of Yo C14, the dead sample will have 0.25Yo of C14.
the rate of decay of radiactive matter over time is
- Y(t) = Yo * e (( - t * Ln2 ) / T)
∴ Y(t) = 0.25Yo; T = 5730
⇒ 0.25Yo = Yo * e (( - t * Ln2 ) / 5730 )
⇒ 0.25 = e (( - t * Ln2 ) / 5730 )
⇒ Ln(0.25) = ( - t * Ln2 ) / 5730
⇒ - 7943.466 = - t * Ln2
⇒ 7943.466 / Ln2 = t
⇒ t = 11460 year
If a given solution has a 30% solute concentration and that more of the solute would be added to the mixture, then the new concentration of the solute would be higher than the original since more solute is present in the solution. Concentration will always be the amount of a substance in a mixture per amount of the solvent or the solution. So, concentration and the amount of solute has a direct relation.

Explanation:
When you are writing a scholarly paper, you have to conduct a thorough search for source materials online. These sources must be reliable, credible and contain verifiable information. In a project such as writing a paper on the topic 'ocean acidification', the following materials are relevant;
Source 1) 'Functional impacts of ocean acidification in an ecologically critical foundation species,'; Brian Gaylord, Tessa M. Hill, Eric Sanford, Elizabeth A. Lenz, Lisa A. Jacobs, Kirk N. Sato, Ann D. Russell, Annaliese Hettinger; Journal of Experimental Biology 2011 214: 2586-2594; doi: 10.1242/jeb.055939
