What is the weight of a mole?
It depends on the atomic mass. Carbon, for instance, is the standard for the mole. One mole of carbon is 12 grams. Other elements will be different. One mole of nickel, for instance, is 58.6934 grams. For other elements, simply look it up on the periodic table.
Does 1.0 mole of carbon contain Avogadro's number of particles?
Yes. 1 mole of all elements (including carbon) or compounds contain Avogadro number of particles (6.023 x 1023 particles)
Is a mole of any element contain Avogadro 's number?
Yes, a mole of any element contains Avogadro's number of atoms, which is approximately (6.022 \times 10^{23}). This constant applies universally to all substances, whether they are elements, compounds, or ions, meaning that one mole of any substance will always contain this specific number of particles.
Why are hydrocarbons elements?
Hydrocarbons are compounds, not elements, composed of hydrogen and carbon atoms. Elements are pure substances made up of only one type of atom, while compounds contain different types of atoms chemically bonded together.
What are some compounds of minerals that occur as elements instead of compounds?
Copper, Silver, and Gold occur as elements instead of compounds.
Why one mole of different compounds have different masses but have same number of molecules?
One mole of different compounds have different masses but have same number of molecules because that is the definition of a mole - a mole is about 6.022x1023 molecules of any particular material - and is normalized to the mass of Carbon-12.
What is the weight of a mole?
It depends on the atomic mass. Carbon, for instance, is the standard for the mole. One mole of carbon is 12 grams. Other elements will be different. One mole of nickel, for instance, is 58.6934 grams. For other elements, simply look it up on the periodic table.
Do compounds only have one element?
No. Compounds can have any number of elements above one.
What if two samples of elements each represent one mole then?
If two samples of elements each represent one mole, then they will contain the same number of atoms. This is because one mole of any substance contains Avogadro's number of particles, which is approximately 6.022 x 10^23. Therefore, both samples will have the same number of atoms, even if they are different elements.
Does 1.0 mole of carbon contain Avogadro's number of particles?
Yes. 1 mole of all elements (including carbon) or compounds contain Avogadro number of particles (6.023 x 1023 particles)
What is the minimum number of moles of O2 required to produce one mole of CO2?
One mole of CO2 requires one mole of O2 to produce during combustion of carbon-containing compounds.
Gold and silver are compounds or elements?
they are elements compounds are when you take two or more elements and mix them together.
How is the mole of a hydrogen the same asa mole of helium?
1 mole of all elements has 6.023 x 1023 atoms (but one mole of each element will weigh different)
How do elements relate to compounds?
Chemical compounds are formed from chemical elements.
What characteristic does one mole of carbon have in common with one mole of sodium?
Both one mole of carbon and one mole of sodium contain Avogadro's number of atoms, which is approximately 6.02 x 10^23 atoms. This quantity is true for all elements or substances when considering one mole.
Is a mole of any element contain Avogadro 's number?
Yes, a mole of any element contains Avogadro's number of atoms, which is approximately (6.022 \times 10^{23}). This constant applies universally to all substances, whether they are elements, compounds, or ions, meaning that one mole of any substance will always contain this specific number of particles.
Most elements are combined with one or more other elements in?
Elements form molecules of chemical compounds
