Question

M 3. Density of a substance is p=V where M = (20 + 0.2)kg and V = (10 + 0.1)m3. Calculate percentage error in 'p'? ​

Answer 1

0%

Explanation:

Density = mass/volume

Now,

percentage error of mass =

(0.2/20)x100 = 1%

percentage error of volume = (0.1/10)x100 = 1%

so,

percentage error of density = % error of mass - % error of volume = 1% - 1% = 0%
