A helium-4 atom is just about 1/3 the mass of a carbon-12 atom.
The atomic mass of Carbon is 12.0107 The atomic mass of Gold is 196.96657 So an atom of Gold is about 16 times heavier than an atom of Carbon.
18.96 times greater = 19.96 times as great.
Mass of Carbon-12 = 12 amu 5times of mass of Carbon-12 atom = 5 x 12 = 60 amu So atomic mass of element X = 60 amu Rachel- www.examville.com ,tutor
the atomic mass carbon is 12.011 g/mol 12.011/mol = the mass of one atom 12.011/6.022x10 raised to the power of 23 this equals 1.994520093 x 10 raised to the power of -23 this is the mass of one atom of carbon in grams.

The Atomic Mass of Carbon is 12.0107 The atomic mass of Gold is 196.96657 So an atom of Gold is about 16 times heavier than an atom of Carbon.
Sulphur has a molar mass of 32.065. Carbon has a molar mass of 12.01. 32.065 / 12.01 = 2.67. So an sulphur atom is 2.67 heavier than an carbon atom.
The atomic mass of Carbon is 12.0107 The atomic mass of Gold is 196.96657 So an atom of Gold is about 16 times heavier than an atom of Carbon.
18.96 times greater = 19.96 times as great.
It isn't. Carbon is 6th on the Periodic Table and Oxygen is 8. Oxygen is the heavier element. mass of oxygen / mass of carbon 15.99g / 12.01g = 1.33 heavier than carbon

Isotope.
Mass of C-12 atom = 12 amu mass of C-12 atom = am So atomic mass of A = 4 amu source ; www.examville.com
