If you have 1.81 10 24 atoms of copper how may moles of copper do you have?
Take that number of copper atoms and divide by "Avogadro's constant," which is the number of representative particles (in this case, atoms) in 1 mole of any substance. Here's the math: 1.8x10e24 / 6.02x10e23 = approximately 3 moles.
Is there an SI unit for number of atoms?
No SI unit for no. of atoms. But there is a SI unit to measure the amount of any substance. It is moles and mole is a fixed quantity. Each mole represents a group of 6.022 x 1023 particles. These particles may be atoms or molecules.
How many particles are there in one mole of a substance?
There may be about 6.022 x 1023 atoms in one mole, but we must ask this question: a mole of what? While a mole of a substance contains about 6.022 x 1023 particles of that substance, the substance may not be composed of single atoms. As this is a critical issue for the budding chemist, let's investigate just a bit.A mole of any substance contains Avagadro's number of "basic units" of that substance. Avagadro's number (or the Avagadro constant) is about 6.022 x 1023 "basic units" of a given substance. In the case of helium, we'll have that many atoms of helium. That's because if we encounter helium floating around in air, it is found in units of single atoms. In the case of hydrogen or oxygen, these gases exist as diatomic molecules. That means there are two atoms in a given molecule of each gas, and there will be 2 times 6.022 x 1023 atoms in a mole of hydrogen or oxygen.Going further, we'll see about 6.022 x 1023 molecules of H2O in a mole of water. Using the logic above, we'll have about 6.022 x 1023 atoms of oxygen in a mole of water, and twice that many atoms of hydrogen in the mole of water.It is critical to the understanding of the chemist to be clear about the mole and what it represents.
Is zirconium poisonous?
The element is noted for its slight toxic ability and is poisonous to humans and anmimals. In a powder form the element is an extreme fire and explosive hazard; it may spontaniously combust at any givin time but is much more likely to explode in warmer tempratures.(note: this element will burn under water)
What is an asymmetrical mole?
A cancerous mole may have two halves of unequal size
What does an irregular mole indicate?
A cancerous mole may have ragged or notched edges.
What is the representative particles for covalent compounds?
You may have gotten this from the Fundamentals Of Chemistry textbook/booklet in the ionic compounds section. The answer is actually in there but here it is again,Particles that are held together by strong electrostatic forces of attraction by positively charged ions.~amanda1rox
How many times may a representative be elected?
As long as he or she is elected to be a representative. There is no limit to how many terms a House of Representative member may be elected.

What chemicals does nitrogen bond with?
Aluminium,titanium, zirconium,calcium,silicon. There may be some others.
What is avocados number?
Avogadro is the name given to the number of atoms (molecules) per mole of a substance.An avocado is some green vegetable. I am not sure about its numerical system.
