What element is 40 amu?
The element with an approximate atomic mass of 40 amu is Calcium (Ca).
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
The molecular formula mass of this compound is 210 amu What are the subscripts in the actual molecular formula Enter the subscripts for C H and O?
Given the molecular formula mass of 210 amu, the subscripts for C, H, and O in the actual molecular formula can be determined as follows: the atomic mass of carbon (C) is 12 amu the atomic mass of hydrogen (H) is 1 amu the atomic mass of oxygen (O) is 16 amu Thus, the subscripts for C, H, and O are calculated as follows: Subscript for C: 210 amu / 12 amu = 17.5 (approx. 18) Subscript for H: 210 amu / 1 amu = 210 Subscript for O: The compound doesn't contain oxygen since the sum of 18 (C) and 210 (H) exceeds 210, which is the given molecular formula mass.
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?
The element with 52 atomic mass units (amu) is Tellurium (Te), which has an atomic number of 52.
What element is 40 amu?
The element with an approximate atomic mass of 40 amu is Calcium (Ca).
What element has 30 electrons and 64 amu?
The element zinc (Zn).
Atomic mass of mercury-?
The atomic mass of the element Mercury is 200.59 amu.
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?
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.
What is the atomic mass of the element beryllium?
9.012182 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
Which elements atomic mass is 222 amu?
The element with an atomic mass of 222 amu is radon (Rn).
Atom of element X has mass 5 times than that of Carbon-12 What is its atomic mass?
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
Which element has 2 istotopes with one 10 amu and the other 11 amu?
Boron is the element that has two isotopes with atomic masses of approximately 10 amu and 11 amu. The most common isotope of Boron is Boron-11, which has an atomic mass of 11 amu, while the less common isotope Boron-10 has an atomic mass of 10 amu.
