A wooden door lintel from an excavated site in Mexico would be expected to have what ratio of carbon-14 to carbon-12 atoms if the lintel were $9.0 \times 10^{3}$ years old?
A sample of wood from an archaeological excavation is dated by using a mass spectrometer to measure the fraction of ${ }^{14} \mathrm{C}$ atoms. Suppose 100 atoms of ${ }^{14} \mathrm{C}$ are found for every $1.0 \times 10^{15}$ atoms of ${ }^{12} \mathrm{C}$ in the sample. What is the wood's age?
How old is a piece of wood that has lost $90 \%$ of its carbon- $14 ?$
