How do you determine the number of atoms in some amount of moles of an atom?
The chemical formula will give the number of atoms in one molecule, then multiply by Avogadro's number (6.022 x 1023). So H2O has 3 atoms (2 hydrogen and 1 oxygen). Multiply 3 by 6.022 x 1023 to get total number of atoms in 1 mole of water.
Define limiting reactant?
In a chemical reaction the limitting reactant is also know as limiting reagent.it is the substance which is totally consumed when the chemical reaction is complete.the reacton can not proceed without it.
Does the amount of water in a cup effect its pH?
pH is the measure of the levels of acid or base in a substance. Increasing the amount of a substance will not change the pH so long as the existing substance and the added substance are chemically the same.
What is molar mass in chemistry?
Complex Answer: Molar mass is the sum of the masses of all the atoms in a compound. Molar mass, is a physical property characteristic of a given substance (chemical element or chemical compound), namely its mass per mole of substance as grams per mole (g/mol or g mol−1), especially in chemistry. A mole is another unit of measurement. It is the quantity of anything that has the same number of atoms found in 12 grams of carbon-12. That number is Avogadro's Number, which is usually stated as 6.022 x 1023.Simple Answer: It is the amount of a substance in moles.
How many atoms of lithium are in 18.7 g?
The gram Atomic Mass of lithium is 6.941; this is the amount of lithium that contains Avogadro's Number of atoms. Therefore, in 18.7 g of lithium, there will be (18.7)/(6.941) times Avogadro's Number of atoms, or about 1.62 X 1024, to the justified number of significant digits.
A mole is an SI base unit that describes the?
A mole is a unit that describes an amount of a substance that has 1 unit of Avogadro's number in it. Avogadro's number is 6.022 E23.
How do you find the amount of molecules in a substance?
The number of molecules in a mol of a substance is the Avogadro number: 6,022 140 857 (74).10e23.
What is amedeo avogadro discovery or invention?
so far that i know of is that he invented 3 things the first was Avogadro's law which is v divided by n=k which states volume of the gas divided by the amount of substance of the gas which equals proportionality constant. the second is Avogadro's number which is which is used to compute the results of chemical reactions. and the third is Avogadro's constant, which is 6.0221415 × 1023 mol-1which basically is gases and molecules. thanks peace love happiness togetherness :)
What determines the amount of chemical energy a substance has?
The amount of chemical energy a substance has is determined by the types and arrangement of atoms and molecules in that substance. The energy is stored within the chemical bonds between these atoms and molecules. The strength of these bonds and the potential energy stored in them determine the amount of chemical energy.
What is avogadro number used for measuring and what is the number?
The Avogadro constant is the number of constituent particles, usually atoms or molecules, that are contained in the amount of substance given by one mole. The number is approx 6.02214086*10^23 mol-1
What is the volume occupied by 2.12 moles of NO?
The volume occupied by 2.12 moles of nitrous oxide is 9.35. A mole is described in chemistry as an amount of pure substance containing the same number of chemical units as there are atoms.
What is the chemical substance present in maximum amount in an animal cell?
2
What evidence in chemical reaction in mole?
Mole is the the unit for amount of substance in SI.
Why do you found it useful to have two units for the amount of substance the kilograms and the mole?
Actually, the kilogram and the mole measure two quite different things. The kilogram is a unit of mass. The mole is a unit of amount of substance, in the sense of the amount of atoms or molecules (in multiples of Avogadro's number). The same amount of kilograms can have varying amounts of moles, for different substances.
What two values are needed to calculate the concentration of a chemical in an organism?
Solubility and amount of the substance
What is the measured amount of a productobtained from the chemical reaction?
This is usually referred to as the ACTUAL YIELD of that substance.
What are two physical properties that can that can vary when the substance with these physical properties that dose not change?
Temperature and amount of the substance do not change chemical properties.
