Ooooh, SO close..... Tungsten has an average Atomic Mass of 183.84, accordng to Webelements.com.
Well, to be precise, no atom has a fractional atomic mass; the fractional numbers are based on proportions of atoms with 74 protons and some varying number of neutrons from 106 to 112 neutrons. The most prevalent numbers are 110, 112, and 108 neutrons, in that order.
Another word for AMU of a element is the Molar Mass of a element.
The atomic mass is calculated by averaging the masses of the isotopes based on their abundance. In this case, 75% of the isotopes have a mass of 35.0 amu and 25% have a mass of 37.0 amu. Atomic mass = (0.75 * 35.0 amu) + (0.25 * 37.0 amu) = 35.5 amu.
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 element with an atomic mass of 222 amu is radon (Rn).
9.012182 amu
Another word for AMU of a element is the Molar Mass of a element.
The element with an atomic mass of 55.85 amu is Iron (Fe).
The atomic mass is calculated by averaging the masses of the isotopes based on their abundance. In this case, 75% of the isotopes have a mass of 35.0 amu and 25% have a mass of 37.0 amu. Atomic mass = (0.75 * 35.0 amu) + (0.25 * 37.0 amu) = 35.5 amu.
The atomic mass of the element Mercury is 200.59 amu.
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 is the mass (weight) of the element measured in atomic mass units (AMU)
The element with 52 atomic mass units (amu) is Tellurium (Te), which has an atomic number of 52.
The element with an atomic mass of 222 amu is radon (Rn).
138.90547 amu
magnesium
9.012182 amu
AMU stands for atomic mass units; the number of units an element has is called its atomic mass. The atomic mass of carbon is exactly 12, by definition.
