Question

if the the mass and volume of an object have 4.27gm and 1.3cm^3then the significant figure is​

Answer 1

Answer:

Here, mass, m=4.237g

Volume, V=2.5cm

3

We know the formula

Density, ρ=

Volume

Mass

=

2.5cm

3

4.237g

=1.6948gcm

−3

As the mass has 4 significant figures and volume has 2 significant figures, therefore, as per rule, density will have only two significant figures. Rounding off to two significant figures, we get, ρ=1.7gcm

−3

Answer 2

5.57^3

it is in correct
