The density of plutonium is 19.84 g/cm². What is its mass if the container has<br> volume of 250 cm?
serious [3.7K]

Answer:

the answer is  7.936X 10⁻⁷kg.... the unit for volume must be cm³

Explanation:

we know,

ρ =m/v

given,

ρ =19.84/1000X(100)²= 1.984X10⁻⁶kg/m²

V (volume of the container means the volume of the element)=2.5 m³

NOW putting in the equation

1.984X10⁻⁶/2.5=m

or, m=7.936X 10⁻⁷kg(ANS)

thank u(i am not 100% sure but think it shoud be the answer)
