If the mass of a material is 99 grams and the volume of the material is 22 cm3, what would the density of the material be?

Kazeer [188]

You are asked to give the answer in <span>g/cm3. So without knowing any single formulae you can just divide grams by cm3.

</span> $\frac{99 grams}{22 cm^{3} }$

= 4.5 g/cm3

GarryVolchara [31]

Explanation:

Kepler’s third law states that for all objects orbiting a given body, the cube of the semimajor axis (A) is proportional to the square of the orbital period (P).

For each of our planets orbiting the Sun, the relationship between the orbital period and semimajor axis can be represented by the equation as:

$P^2=kA^3$

k is constant of proportionality

It is required to solve the above equation for k

$k=\dfrac{P^2}{A^3}$
