Atomic Mass of copper is 63. 546amu where amu is Atomic mass unit
What else can I help you with?
If a sample of copper contains 1.76E 4 atoms of copper-63 and 7.88E 3 atoms of copper-65 what is the percentage of copper-63 atoms in the sample?
To find the percentage of copper-63 atoms in the sample, first add the number of copper-63 and copper-65 atoms together (1.76E4 + 7.88E3). Then, divide the number of copper-63 atoms by the total number of atoms and multiply by 100 to get the percentage. In this case, the percentage of copper-63 atoms in the sample is approximately 69.0%.
All isotopes of the element copper contains?
There are 29 isotopes of copper, with mass numbers ranging from 52 to 80. However, only two isotopes, copper-63 and copper-65, are stable. The most abundant isotope is copper-63, making up about 69% of naturally occurring copper.
What is different in the two isotopes of copper?
that one has a bigger mass than the other one for example one has 63 and the other has 65.They have equal number of protons and electrons.Their mass differs due to presence of different number of neutrons.
How many neutrons does a Cu 1 have?
29. Cu 1 is an ion where the Cu atom has lost an electron. Therefore, it would have the normal 29 neutrons.
How many protons neutrons and electrons does copper?
Copper has 29 protons and 29 electrons. The number of neutrons can vary depending on the isotope of copper. The most common isotope, copper-63, has 34 neutrons.

The relative percentage abundance of the two isotope of copper?
Copper has two stable isotopes, copper-63 and copper-65. The relative percentage abundance of these isotopes is approximately 69.17% for copper-63 and 30.83% for copper-65.
Calculate the average atomic mass of copper-63 and copper-65?
The average atomic mass of copper is 63.55 g/mol. This value is calculated by taking a weighted average of the masses of copper-63 and copper-65, based on their natural abundances in a sample of copper. Copper-63 has a natural abundance of 69.17%, while copper-65 has an abundance of 30.83%. Calculating the average atomic mass would involve multiplying the atomic mass of each isotope by its natural abundance, and then summing the results.

How many isotopes does copper have?
Copper has natural isotopes of 63,67. And other isotopes are known at least from 58 through 70. But these are unstable.
Average atomic mass of copper is 63.5 amu It exists as two isotopes and Calculate the percentage and ratio of copper isotopes?
Let percentage of = xPercentage of = 100 -xFrom above, average atomic mass= amuBut given average atomic mass = 63.5 amuTherefore,Percentage = 75Percentage of = 100 -75 =25Ratio of and = 75:25=3:1source : www.examville.com
