. An analytical balance is used with brass weights. Find the mass of a body made of Plexiglas, whose two measurements result in a difference of at least one mark if one measurement is performed in dry weather and the other in wet weather? In both cases the room temperature is 23 C and the atmospherie pressure is 10 Pa. In wet weather the pressure of the water vapour in the air is 2 0 Pa. The sensitivity of the balance is 0.l mg/scalemark. ( e =8.5-10 kg/m: gPlexiglns = 1.18-10 kg/m".)
