What element is 55.85 amu?
Fe
What is the AMU of carbon?
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.
What is the atomic weight of an element that has two isotopes one with a mass of 30 amu and the other with a mass of 32 amu?
The atomic mass of the element cannot be discovered with the given information. It was not specified as to the ratio of the isotopes of the element. If they two isotopes are equally represented, then it's half the sum of the masses of the two isotopes, which is 63 + 65 = 128, and 128 / 2 = 64 amu.If another ratio (or perhaps a percentage) of the isotopes if given, then a calculation can be made to discover the atomic mass of the element. This calculation will reflect the different amounts of the two isotopes present in samples of that element.Added:Though the answer given here is correct for the question stated above, there is a more clearing answer for the suggested question: Which element has two isotopes .... (etc.). This is typically true for copper, Cu, atom no. 29, of which two natural occurring isotopes exist:Cu-63, mass 62.92960 a.m.u., occurrence 69.1%Cu-65, mass 64.92779 a.m.u., occurrence 30.9%The average (relative) atomic mass = 63.55
What is the percentage of composition of hydrogen in C3H4?
Ethylene- C2H4 Find the atomic masses for each element and multiply it by the number of atoms in the compound, then add. C- 12.0 * 2= 24.0 H- 1.00 * 4= 4.00 ----------------------- 28.0 Take the masses for each element and divide it by the total mass. Then change the answer to get the percent. C 24.0 / 28.0= .857 = 85.7% H 4.00 / 28.0= .143 = 14.3% Ethylene is 85.7% Carbon and 14.3% Hydrogen
In the compound Cu2OH2CO3 which element is present with the largest percent by mass?
From the formula of the compound, each molecular unit contains 2 copper atoms, 4 oxygen atoms, one carbon atom, and 2 hydrogen atoms. Multiplying each of these by its corresponding atomic mass gives 127 atomic mass units ("amu") of copper, 64 amu of oxygen, 12 amu of carbon, and 2 amu of hydrogen. Copper is clearly present in the largest percent by mass.
What is another name for the AMU of an element?
Another word for AMU of a element is the Molar Mass of a element.
What is the element with 52 amu?
Chromium has 52 amu.
What element is 55.85 amu?

What element has amu 20 and is a gas?
Neon
If 75 percent of the isotopes of an element have a mass of 35.0 amu and 25 percent of the isotopes have a mass of 37.0amu what is the atomic mass of the element?
35.5 amu
What element has atoms which have a mass of 12 amu?
magnesium
What is the atomic mass of the element Lanthanum?
138.90547 amu
