Question

The measured mass and volume of a body are are 2.00g and 5.00cm3 respectively with possible error of 0.01g and 0.1cm3. what would be the percent error in density

Answer 1

Answer:

Explanation:

Mass = 2g and error is 0.01g

Volume = 5cm³ and error is 0.1g

D=m/v

D=2/5=0.4g/cm³

Error....

Delta Đ /D=deltam/m + delta v/v

Shifting D to other side...

=( 0.01/2 + 0.1/5) *D

= 1/40*0.4

Therefore maximum permissible error is

0.01

And density is 0.4+- 0.01g/cm³
