What mass of solid lead would displace exactly 234.6 liters of water?

The answer is 2660.6 kg

Exactly 234.6 liters of water is displaced by lead hence giving us the volume of the metal, according to Archimedes' principle of displacement.

Lead has a density of 11341 kg/m3 and we know that 1000L = 1m3. Therefore;

234.6 liters = 0.2346m3

0.2346 * 11341

= 2660.6 kg

.
