manganese #25 on the periodic table has three isotopic forms. Find it’s average atomic mass if Mn-53 has a mass of 53.02975 amu occurs 20.75%

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer

plz give brainliest

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.

the answer is a for sure mark brainliest i had got this right on usatestprep
