Answer = Gravity is measured by the acceleration that gives to freely falling objects.
Here are some rules:
1. The oxidation state of a free element (uncombined element) is zero.2. For a simple (monatomic) ion, the oxidation state is equal to the net charge on the ion.3. Hydrogen has an oxidation state of +1 and oxygen has an oxidation state of −2 when they are present in most compounds.
The oxidation number of Fe in Fe(NO3)2 is +3.
STEP-BY-STEP EXPLANATION
What to find? Mass number of an element
Given parameters
Number of protons = 15
Number of neutron = 16
Number of electrons = 15
Considering the atomic struc
The formula for calculating the mass number of an element is given below as
The next thing is to substitute the
Given:
m = 3 x 10³⁶ kg, the mass of the star
r = 7.6 x 10⁵ km = 7.6 x 10⁸ m
Calculate the volume of the star (as the volume of a sold sphere).
Calculate the density the star.
By definition, the density of the star is
In g/cm³, the density is
Answer: 1.6315 x 10⁶ g/cm³
