Explanation:
myo means "of muscle" or "relating to muscle"
cardium denotes tissues or cells that are associated with the heart.

These cells/tissues are hugely important for the normal functioning of the heart, and disruption is associated with diseases such as ischemic heart disease.
The average atomic mass of the imaginary element : 47.255 amu
<h3>Further explanation </h3>
The elements in nature have several types of isotopes
Isotopes are elements that have the same Atomic Number (Proton)
Atomic mass is the average atomic mass of all its isotopes
Mass atom X = mass isotope 1 . % + mass isotope 2.% ..
isotope E-47 47.011 amu, 87.34%
isotope E-48 48.008 amu, 6.895
isotope E-49 50.009 amu, 5.77%
The average atomic mass :
