Option (C) is correct. For any marked measuring device, one place beyond the numerical place of the marking is estimated, and this determines the correct number of significant figures. If the thermometer is marked to 0.1°Czero point one degrees Celsius, the hundredth place should be estimated and the temperature recorded as 22.44°C22 point four four degrees Celsius. A thermometer inserted into a solution has a mercury level of just a bit less than halfway between the markings for 22.4ºC22 poi...
