It's the eye because it's the organ of sight
M=7M(H₂O)
M=7*18.015 g/mol = 126.105 g/mol
I believe it’s a positive charge
1.Molar mass is the mass of one mole per single element while atomic mass is the mass of an atom at rest or is the number of protons and neutrons.
2.Molar mass is measured in grams per mole while atomic mass is “unitless.”
3.Atomic mass is measured via mass spectrometry while molar mass is computed via atomic weight.
i think it’s D , not sure though
