Why do chemists use relative mass of atoms compared to a reference isotope rather than the actual masses of the atoms?
i need a answer goish just tell me Edit :: This looks suspiciously like a homework question. It wouln't be called the "Average Atomic Mass" if it wasn't the average of all the isotopes, now wouldn' it?
What else can I help you with?
Why do chemists use relative masses of atoms compared to a reference isotope rather than absolute masses in their calculations?
Chemists use relative masses of atoms compared to a reference isotope because it allows for easier comparison and calculation of chemical reactions. Absolute masses can vary, but relative masses provide a consistent point of reference for analysis.
How to find the relative abundance of an isotope?
To find the relative abundance of an isotope, you can use a mass spectrometer to measure the mass-to-charge ratio of the isotopes present in a sample. By comparing the intensity of the peaks on the mass spectrum, you can determine the relative abundance of each isotope.
State the name and the mass of the isotope relative to which all atomic masses are measured?
The isotope used as the reference for atomic masses is carbon-12, with a mass of 12 atomic mass units (amu).
What changes in an isotope as compared to its parent element?
An isotope differs from its parent element in the number of neutrons in its nucleus, which can affect its stability and properties.
What does the relative abundance tell you?
Relative abundance refers to the proportion of a particular species in a community compared to the total number of individuals. It can give insights into the diversity, distribution, and ecological interactions within an ecosystem. By analyzing relative abundance, researchers can understand species composition and estimate the impact of certain species on the overall ecosystem.

Why do chemist use relative masses of atoms compared to a reference isotope rather than the actual masses of atoms?
because, the mass of an atom is too small to be easily used as a point of reference. Comparing it to the C-12 atom (so relative Atomic Mass) is much easier. I think this is the answer.
How can the relative and absolute ages of rock be determined?
By comparing the relative percentages of a radioactive (parent) isotope and a stable (daughter) isotope.
The weights of all elements are always compared to oxygen. True False?
True. In chemistry, the weights of all elements are often compared to oxygen, specifically the isotope oxygen-16, which is used as a standard reference point for calculating atomic weights. This practice allows for a consistent and relative comparison of the masses of different elements.
What isotope of carbon has been chosen as the reference isotope for atomic mass units?
The atomic mass may be considered to be the total mass of protons, neutrons and electrons in a single atom (when the atom is motionless). Relative isotopic mass is the relative mass of a given isotope scaled with carbon-12 as exactly 12.

The atomic mass unit is presently based on assigning an exact integral mass to an isotope of what?
The atomic mass unit is based on assigning an exact integral mass to the carbon-12 isotope. This isotope was chosen as the reference because it is abundant in nature and has a relative atomic mass very close to 12.
Why must radioactive decay must be constant in order for radioactive dating to be accurate?
Amount of certain radioactive isotope in an object is compared with a reference amount. this ratio can then be used amount.
Why must radioactive decay must be constant in order for radiometric dating to be accurate?

Europium has a mass of 150.9196amu and a mass of m152.9209amu the average atomic mass of Eu is 151.96amu calculate the relative abundance of the two europium isotopes?
Let x represent the relative abundance of the isotope with mass 150.9196 amu and 1-x represent the relative abundance of the other isotope with mass 152.9209 amu. The average atomic mass formula is [(mass isotope 1)(abundance isotope 1) + (mass isotope 2)(abundance isotope 2)] = average atomic mass. Substituting the values given, you can set up a system of equations and solve for x to find the relative abundance of each isotope.
State the name and the mass of the isotope relative to which all atomic masses are measured?
The isotope used as the reference for atomic masses is carbon-12, with a mass of 12 atomic mass units (amu).
What is relative decay?
Relative decay is the process of determining the age of a sample by comparing the amount of a radioactive isotope it contains to the amount of its decay products. By measuring the ratio of remaining isotope to decay product, scientists can estimate the age of the sample based on the known decay rate of the isotope.
