Based on the stars size (width+length) approx.
Explanation:
Atomic number , protons and electrons have the same value / their value is same .
But for the neutron there is no specific technique. You have to remember the neutrons of every element
The compound formed is KCl, called potassium chloride.
Amino acids are Proteins,
Lipids are Fatty acids
Nucleic acid which have nucleotides and, build RNA and DNA
Starches are a cause of Carbohydrates, after lots of Polymers.
So, therefore the answer is a)
If we are given the mass, the volume that the certain substance occupies is calculated by using the density in the equation,
V = m/D
where V is the volume, mi s the mass, and D is density. From the reliable sources, the value of the density of the substance is equal to 2,700 kg/m³.
Substituting the known values from to the equation,
V - (6.56 kg)/(2700 kg/m³)
V = 2.429 x 10^-3 m³
Answer: 2.429 x 10^-3 m³
