The mass of a body is 20.000 g and its volume is 10.00 cm3. If the measured values are expressed to the correct significant figures, the maximum error in the value of density is

Maximum error in measuring mass = 0.001 g, because least count is 0.001 g, Similarly, maximum error in measuring volume is 0.01 cm3.Δρρ=ΔMM+ΔVV=0.00120.000+0.0110.00                                =5×10−5+1×10−3=1.05×10−3Δρ=1.05×10−3×ρ     =1.05×10−3×20.00010.00=0.002gcm−3
