How many moles are equal to 3.25×1024 atoms of mercury? Avogadro Number:A constant number that illustrates the number of particles existing in the unit mole of the material is known as the Avogadro number. The unit to describe the Avogadro number is atoms per mole....
In salt (sodium chloride) there are equal numbers of sodium and chlorine atoms (NaCl), so the ratio is 1:1. We can easily explain this if chemical elements really exist as simple particles (atoms, in other words), which snap together like building blocks. Some substances are radioactive:...
Consider a 300 g sample of silver. How many silver atoms are in the sample? What mass of copper would be required for the copper sample to have the same number of atoms as the silver sample? What is the mass, in...
Technically, ions, molecules, and compounds are all atoms. Usually, however, when someone talks about an atom example they mean a single particle of an element. Most often, this means a neutral atom, which has an equal number of protons and electrons and lacks a net electrical charge. Sourc...
What are the total number of moles of atoms in 4.32 g of Sc(NO3)3? (Atomic weights: Sc = 45.0, 0 = 16.0, N = 14.01). A0.0132 B0.324 C0.0187 D0.243Submit What is the total number of atoms present in 25.0 mg of camphor, C10H16O? A9.89×1019 B6.02×1020 C9.89×1020 D2.67×...

How many atoms are in 1.44 moles of Mg? What mass in mg does 2.63 moles of Ni have? How many moles of magnesium (Mg) are there in 80.3 g of Mg? Convert 0.6319 grams of Mg to moles of Mg. How many moles are equal to 0.357 mg of NH2CH2COOH? Calculate the number of moles o...
5 moles of P4O10 * 4 P atoms= 20 moles of P (20 moles) * (6.023 * 10^23atoms/mole) = 1.2046 *10^25 atoms. Which doesn't make any sense to me at all. And then my teacher said something like I had the general IDEA of how to answer the problem (which I totally don't) ...
