Answer :
The proton is not a fundamental particle, being composed of quark–gluon matter. Its size is approximately 10^−15 meters and its density 10^18 kg/m^3.
order-of-magnitude:
An exponential change of plus or minus 1 in the value of a quantity or unit is defined as an order of magnitude. The phrase is typically used in connection with scientific notation with powers of 10. The usage of orders of magnitude helps people understand and have a better grasp on the size of numbers and other quantities.
The mass of a proton to be 1. 67×10^−27 kg, the order of magnitude of the number of protons in 1 g is 5.
Density Equation for these Calculations:
p=m/V
Where:
p = density
m = mass
V = volume
The formula used by the density calculator is p=m/V, or density (p) equals mass (m) divided by volume (V) (V). Any two of the values can be used by the calculator to determine the third. Mass per unit volume is the definition of density. This calculator will convert between units when you enter data along with the known units of measurement for each.
