The International Annealed Copper Standard (IACS) defines $100\% \text{ IACS}$ electrical conductivity as $5.80 imes 10^7 \text{ S/m}$. If a titanium alloy is measured to have a conductivity of $3.50\% \text{ IACS}$, what is its electrical resistivity in nanoohm-meters ($1 \text{ n}\Omega\cdot\text{m} = 10^{-9} \text{ } \Omega\cdot\text{m}$)?
