What is the mole ratio of potassium chloride?
1:1, one mole potassium to one mole chlorine
What number represents the word mole?
No number since mole is an animal.
What is meant by the Avogadro number and why is it relevant to the mole?
Avogadro's number is the number of atoms or molecules of a substance that are present in one mole of that substance. It is relevant to the mole by its very definition!
Why mole fraction does not dependend upon temperature?
because mole fraction doesnot depend on volume
How many in a mole?
6.02x1023
What in chemical equations provide mole ratios that can be used as conversion factors?
Coefficients
The coefficients from a balanced equation are used to write conversion factors called?
stoichiometric coefficients.
What are used as conversion factors for determining how much of an element is produced in a chemical reaction?
mole ratio of two substances in the balanced equation.
What are the two equivalent conversion factors for the molar mass of silver?
The molar mass of silver is 107.87 g/mol. Therefore, the conversion factors are: 1 mol Ag = 107.87 g Ag and 107.87 g Ag = 1 mol Ag.
What is a tremole?
tremole is a type of "three mole" if you will, which is pronounsed tres mole. So obviously tremole is three moles.
1.61 mole percent to PPM?
1.61 mole percent is equivalent to 16,100 parts per million (PPM). This conversion is based on the fact that 1 mole percent is equal to 10,000 parts per million.
What are two forms of the conversion factor that will convert one mole to number of objects and number of objects to one mole?
To convert from moles to number of objects, the conversion factor is Avogadro's number (6.022 x 10^23 objects per mole). To convert from number of objects to moles, the conversion factor is the reciprocal of Avogadro's number (1 mole per 6.022 x 10^23 objects).
How many moles of oxygen are in one mole of calcium carbonate?
There are three moles of oxygen atoms in one mole of calcium carbonate (CaCO3). This is because there are three oxygen atoms in each molecule of calcium carbonate.
A conversion factor derived from the coefficients of a balanced chemical equation interpreted in terms of mole?
A conversion factor for a balanced chemical equation is derived by comparing the coefficients of the reactants and products. In terms of moles, this conversion factor allows us to relate the number of moles of one substance to another in a chemical reaction. It is used to convert between the amounts of different substances involved in the reaction.
What conversion factor is used when converting moles to mass?
The conversion factor used to convert moles to mass is the molar mass of the substance, which is the mass of one mole of the substance expressed in grams per mole. To convert moles to mass, you multiply the number of moles by the molar mass of the substance.
What is a chemical mole?
In Chemistry, we measure things in u(unified mass), but this is really really really small. It is not a practical way to talk about things. (I mean, do you know what 3 u's looks like, cuz i don't) A man named Avogadro came up with a better system. He discovered how many atoms it takes to convert u's to grams. This way you can work with larger amounts than only a few atoms. It turns out that exactly 6.022 x 10 ^23 atoms will convert u's to grams. So, let's first understand u's. These values are unique for each atom, molecule, compound etc.... For atoms, the magnitude (value) can be found on the Periodic Table. For example Cl is 35.45 u. In context(questions): 1. How many ATOMS are in one mole of Chlorine? This is tricky only because there is extra information. A mole of any substance has the same number of atoms (6.022 x 10 ^23), because it is the conversion. The number of atoms in a mole doesn't ever change. 2. How many GRAMS ar in 2 moles of Chlorine? 70.90 grams. One mole contains 35.45, so two moles is twice that number, 70.90. 3. How many moles are in 90.0 grams of Cl? approx. 2.54 moles. This is backwards from the last question. Take the 90.0 grams and divide it by the number of grams in one mole (35.45). My suggestion to you is that you should use conversion factors. If you can successfully do this you won't even have to understand why you are doing what you are doing. (Note: make sure you understand conversion factors first. The units must cancel. Any con. factor can be flipped) Some useful conversion factors: 1 mole/ 6.022 x 10 ^23 atoms #(off of periodic table)/ 1 mole #in U's = # in grams so #in u /# grams ECT.. Good Luck. This is a tough topic for a lot of Chemistry students.
At what age do pupils read Adrian mole?
13 and three quarters
