Answer:

d. 2.14 x 10⁻⁴ kg/m³

Explanation:

Density is defined as the mass of an object per unit volume occupied by that object. The formula of density is, therefore, given as follows:

[tex]\rho = \frac{m}{V}[/tex]

where,

ρ = density of platinum band = ?

m = mass of platinum band = 3 x 10³ kg

V = Volume displaced by Platinum band = 1.4 x 10⁷ m³

Therefore,

[tex]\rho = \frac{3\ x\ 10^{3}\ kg}{1.4\ x\ 10^{7}\ m^{3}}\\\\\rho = 2.14\ x\ 10^{-4}\ kg/m^{3}[/tex]

Hence, the correct option is:

d. 2.14 x 10⁻⁴ kg/m³
