Average atomic mass of copper is 63.5 amu It exists as two isotopes and Calculate the percentage and ratio of copper isotopes?
Greenr1981
Let percentage of = x
Percentage of = 100 -x
From above, average Atomic Mass
= amu
But given average atomic mass = 63.5 amu
Therefore,Percentage = 75
Percentage of = 100 -75 =25
Ratio of and = 75:25=3:1

How you calculate the relative atomic weight of uranium?
The atomic weight of an element is derived from the atomic masses of the isotopes of this element and from the percentage of these isotopes. The correct terms are: - atomic weight for elements - atomic mass for an isotope
Average atomic mass of an element?
"The average atomic weight (not mass) of a chemical element is calculated considering the percentage of each natural isotope and the atomic masses of these isotopes."
How much effect do high percent abundance isotopes have on the average atomic mass of an element?
This entirely depends on the percentage of the different isotopes present. This is typically determined through mass spectrometry. After the percentages of the different isotopes are known, one times the percentage of each isotope by its relative atomic mass, then add this all together. After dividing this by 100, you will have attained the average atomic mass of a naturally ocurring element.
What is the average atomic mass of an element with two isotopes of 220 and 250?
To calculate the median atomic weight, the relative abundance of each isotope could be calculated or given.
How is the atomic mass of each element on the periodic table calculate?
The atomic mass listed on most periodic tables is actually the average atomic mass representing the average atomic masses of the various isotopes of an element depending on their percent natural abundance. Refer to the answers.com question: What is the formula for finding average atomic mass? for a detailed explanation on how to calculate this value.

What information about an element's isotopes is needed to calculate that element's average atomic mass?
the atomic number of each isotope-apex;)
How do you calculate the atomic mass of an element containing a mixtures of isotopes?
weighted average of the various iisotopes
Average atomic mass of an element?
"The average atomic weight (not mass) of a chemical element is calculated considering the percentage of each natural isotope and the atomic masses of these isotopes."
What ios the average atomic weight?
The average atomic weight of an element is the average of all the known isotopes of that element along with their popularity. It would be calculated by gathering all the known isotopes of one element and individually multiplying them by percentage of occurrence.
How much effect do high percent abundance isotopes have on the average atomic mass of an element?
This entirely depends on the percentage of the different isotopes present. This is typically determined through mass spectrometry. After the percentages of the different isotopes are known, one times the percentage of each isotope by its relative atomic mass, then add this all together. After dividing this by 100, you will have attained the average atomic mass of a naturally ocurring element.
Which is the average of the mass numbers of an element's isotopes?
the Atomic Mass
What is the average atomic mass of an element with two isotopes of 220 and 250?
To calculate the median atomic weight, the relative abundance of each isotope could be calculated or given.

(What_is_the_formula_for_finding_average_atomic_mass)
How do you calculate the atomic mass of an element with different isotopes?
To calculate average atomic mass from different isotopes of an element, we take into account the relative atomic masses of isotopes and their relative abundance on Earth. The following formula is used to calculate the needful : atomic mass = mass of isotope x percent abundance + mass of isotope x percent abundance / 100 (whole expression divided by 100)
Why do scientist use weighted average instead of straight mathematical average of masses of isotopes to indicate the atomic mass of an element?
The percentage of each isotope is different.
How does the average atomic mass of an element differ from the mass of an individual atom of the same element?
The masses and relative abundances of all naturally occurring isotopes of the element are required to calculate average atomic mass of the element.
