Question

The density ρ of a piece of metal of a mass

m and volume V is given by m

v

ρ =

if m = 350.45 ± 0.01g, v = 125.32 ± 0.01

cm3 Find % error in ρ.​

Answer 1

Answer:

∆ρ/ρ ×100 = ∆m/m×100÷∆v/v×100

therefore ∆ρ/ρ×100 = ( 0.01/350.45×100 ) /

(0.01 /125.32×100 )

therefore

∆ρ/ρ×100 = 0.228 %
