The element boron has only two stable isotopes one stable isotope has a mass number of 10 and the other has a number of 11. what could be the atomic weight of the element?
From what I remember of chemistry, the amu of each element on the periodic chart is a weighted average of all the isotopes of that element. So, as you indicated - 80.2% of Boron exists as B-11 and 19.8% of boron exists as some other isotope. In that case you can get an estimate of the amu of the unknown through simple math: 0.802*(11.01 amu) + 0.198*(X amu) = 10.81 Solving for x, you get 10.00 amu
What is the mass number of an atom of tin that has 70 neutrons?
The atomic mass of Yb is 173.04 AMU.
What is the amu of a proton?
One proton (at rest) has a.m.u. of 1.007276 which is 1.67262*10-27 kg
How is carbon dioxide and oxygen different?
Carbon Dioxide: Is a compound, which is made up of one carbon atom and two oxygen atoms. Its atomic mass is 44 amu. Plants inhale carbon dioxide during the day and exhale it during night time. All animals exhale it at all times. Oxygen: Is an element, which exists as gas of diatomic molecules (a molecule made up of two atoms of the same element.). It's atom's mass is 16 amu, and mass of the diatomic molecule is 32 amu. Plants exhale it during the day and inhale it during night. All animals inhale it at all times. For other technical differences, you should check other websites :)

An element on the periodic table has two naturally occurring isotopes one isotope has an atomic mass of about 10 amu the other isotope has an atomic mass of about 11 amu what is the name of this eleme?
Boron.
How do you find the moles of a given element?
One takes the atomic mass of that element (the number under the element on a periodic table, measured in amu). That number is the number of grams of the element it takes to make one mole. in other words:X grams (of element)(Atomic Mass of element)= --------------1 mol (of element)

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 unit is used to meause weighted average atomic mass?
Relative atomic mass (RAM) has no unit, it's just a set of numbers, one for each element
Does Kairi come back to see Amu?
No, but in one episode Amu and Tadase are chosen to represent their school for this one event and Kairi is a representative for his school. Naturally, they see each other there.
How many amu's are in one gram?
The equivalent is 0,6.10e24 amu.
Which one is better for ballb - jamia or amu?
No doubt , AMU
Does one helium 4 atom equal one amu?
No. It equals 4 amu.
Who is the best for amu in the Shugo Chara series?
the best for amu is the one that she loves the most.it's amu that need to chose.
What does the mass number represent?
The mass number represents the weight of the protons and neutrons in Atomic Mass units (AMUs). One AMU is equal to one proton or neutron.The average mass of all isotopes of the element - apex.
