What is the density of bone with a mass of 192g and volume of 120cm

The answer is density is equal to 1.6g/cm^{3}

Explanation:

Density is a scalar magnitude referred to the amount of mass in a given volume of a substance or solid object.

To calculate the density of an object, its mass is divided by its volume. If the mass is measured in grams and the volume in cubic centimeters, the unit of density is grams per cubic centimeter (g / cm3)

We use the formula where (d) is density (m) is mass (v) is volume

your answer would be a. 12.5 kg

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
