How many atoms in 1 mole?
There are 6.02 x 10 ^ 23 atoms or molecules of a substance in one mole of that substance. This is Avogadro's number.
How are molarity and molar mass related for a compound?
The molar mass of a substance is measured in grams per mole written as gmol-1. It is worked out using the Mole formula by dividing mass in grams by the amount in moles.
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!
How do you convert 40 mmol of Sodium to grams?
A mole is 6.022*10^23 of a substance. An element's atomic mass, the number below the element's atomic symbol on the periodic table, is the number of grams one mole of that substance weighs. Multiply the number of moles of substance (here, 40 if you meant 40 moles or .04 if you meant millimoles) by the atomic mass of the substance (here, sodium's is 22.98977) to get the final answer in grams.
What does an Avogadro's number of a substance is called a mole mean?
It is the number of particles in a mole of any substance
Define one mole of a substance applied to atomic structure?

What the abbreviation of amount of a substance?
mole
Why is Avogadro's number used to relate the number of particles in 1 mole?
By definition the Avogadro number is the number of molecules in 1 mole of substance; the value is 6,022 140 857(74).10e23.
What is mole percent?
Mole percent, or molar percent of a substance is the ratio of the moles of a substance in a mixture to the moles of the mixture. It represents the number of moles of a substance in a mixture as a percentage of the the total number of moles in the mixture. Mole % = (mol substance in a mixture) / (mol mixture) * 100

1 mole of any substance has 6.022 x 1023 atoms or molecules of that substance
What evidence in chemical reaction in mole?
Mole is the the unit for amount of substance in SI.
Molar is the total combined mass of a mole of a substance?
mass
What is the SI base unit used to measure the amount of substance?
The base unit for the amount of a substance is an hour.
how do we measure how much of a substance we have?
Molar mass of a substance is the mass of one mole of the substance in grams. It has a unit of grams per mole (g mol -1). One mole of any substance contains 6.02 × 10 23 particles. Therefore, the molar mass of a substance contains 6.02 × 10 23 particles of the substance.
