Step by step solution

Step 1:Time in years at one half-life

¹⁴C has a half-life of 5,730 years.

Time in years at one half-life would be 5,730.

Time in years at two half-lives

Years in number of half-lives = Half-life X Number of half-lives

Years at two half-lives $= 5,730 \times 2 = 11,460$

Time in years at three half-lives

Years at three half-lives $= 5,730 \times 3 = 17,190$

Time in years at four half-lives

Years at four half-lives $= 5, 730 \times 4 = 22, 920$

Time in years at five half-lives

Years at five half-lives $= 5, 730 \times 5 = 28, 650$

Time in years at six half-lives

Years at six half-lives $= 5, 730 \times 6 = 34, 380$

Time in years at seven half-lives

Years at seven half-loves $= 5, 730 \times 7 = 40, 110$

Time in years at eight half-lives

Years at eight half-lives $= 5, 730 \times 8 = 45, 840$

Time in years at nine half-lives

Years at nine half-lives $= 5, 730 \times 9 = 51, 570$

Time in years at ten half-lives

Years at ten half-lives $= 5, 730 \times 10 = 57, 300$
