Determine the empirical formula of (a) the rodenticide (rat killer) warfarin, which consists of $74.01 \%$ C, $5.23 \% \mathrm{H}$, and $20.76 \% \mathrm{O}$, by mass; (b) the antibacterial agent sulfamethizole, which consists of $39.98 \% \mathrm{C}$, $3.73 \% \mathrm{H}, 20.73 \% \mathrm{~N}, 11.84 \% \mathrm{O}$, and $23.72 \% \mathrm{~S}$, by mass.

The filament in an incandescent light bulb is made from tungsten metal $\left(d=19.3 \mathrm{~g} / \mathrm{cm}^3\right)$ that has been drawn into a very thin wire. The diameter of the wire is difficult to measure directly, so it is sometimes estimated by measuring the mass of a fixed length of the wire. If a $0.200 \mathrm{~m}$ length of tungsten wire weighs $42.9 \mathrm{mg}$, then what is the diameter of the wire? Express your answer in millimetres.
