Question

a body of mass 4.237gram has volume 2.51cm³ find its density correct to significant figure​

Answer 1

Answer:

1.7 g cm

−3

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

Answer:

2

Explanation:

density = mass/volume = 4.237*2.5 = 1.6948 g cm^-3 = 1.7 g cm^-3

as the minimum significant figure is 2
