What does the relative atomic mass of an element tell us about the relative abundance of an isotope?
None. The relative abundance of isotopes is used to calculate the Average Mass (by multiplying the Atomic Mass of the isotopes by their relative abundancies and adding the products together) while the Atomic Mass is simply the number of protons plus the number of neutrons.
What is the atomic number of CH4?
CH4 is the compound methane. It does NOT have an atomic number. However it has a Relative Molecular Mass (Mr). To calculate its Mr ;- First refer to the Periodic Table for the Atomic Masses of each element present. We have in CH4 ;- 1 x C = 1 x 12 = 12 4 x H = 4 x 1 = 4 12 + 4 = 16 This is the Mr( Relative Molecular Mass ) of methane ; NOT atomic mass.
What do compounds make up?
A compound is a substance formed from two or more elements chemically united in a fixed proportion; a mixture Example: a compound of hydrogen and oxygen resources: a oxford dicitonary
How the you use the percent composition in every day?
You can use percent composition to see how much much flour contributes to the mass of an overall cake. You can see how much kool aid powder is in a given amount of kool aid drink, in percentage. Percentage composition can be used for virtually anything that has a mixture of things. So you don't always have to think percentage composition refers to chemical compounds, such as H2O or KMnO4.
Explain why most carbon compounds are classified as organic compounds?
Organic compounds are compounds necessary to life, and most macromolecules necessary to life contain carbon.
What is the at formula used to calculate the percentage composition of a specific element in a compound?
The at formula is used to calculate the percentage composition of a specific element in a compound. It is calculated by dividing the atomic mass of the element by the molar mass of the compound, and then multiplying by 100 to get the percentage.
Calculate the percentage by the mass of each element in the following compounds:(g) ethanedioic acid,(COOH)2(h)ethanoic acid, CH3COOH(i) lead nitrate, Pb(NO3)2(j) potassium hydrogencarbonate,KHCO3?
(Atomic masses : C=12u;H=1u;O=16u)
How do you calculate the atomic mass of carbon?
The same way you calculate the atomic mass of other elements.
How to calculate neutron?
Atomic mass - Atomic number
How do you convert between the molar percentage of a compound e.g. CaO and the atomic percentage of the elements e.g. Ca and O?
To convert from the molar percentage of a compound to the atomic percentage of its elements, you can use the molar mass of each element to calculate the number of moles of each element in one mole of the compound. Then, you can use these values to determine the atomic percentage of each element. For example, in CaO, one mole of CaO contains 1 mole of Ca and 1 mole of O. So, the atomic percentage of Ca would be (molar percentage of CaO) * (molar mass of Ca) / (molar mass of CaO), and similarly for O.

What is atomic number of mercury tetra thiocynatecobalt 2?
Only elements have atomic numbers, not compounds.
What is calcite atomic number?
Calcite is a compound. Atomic number is appropriate only for elements, not compounds.
How do you calculate the protons from the atomic number?
The atomic number is the number of protons.
Are all elements are compounds?
No. Elements are composed of atoms that have the same number of protons (atomic number) in their atomic nuclei. Compounds are composed of two or more elements that are chemically combined.
Are all elements compounds?
No. Elements are composed of atoms that have the same number of protons (atomic number) in their atomic nuclei. Compounds are composed of two or more elements that are chemically combined.
