What is the relationship between Avogadro’s number and the Mole?
Explanation: One mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions). The number 6.022 × 10²³ is known as Avogadro’s number or Avogadro’s constant. The concept of the mole can be used to convert between mass and numberof particles..
What is the relationship between Avogadro’s number and one mole quizlet?
What is the mathematical relationship between Avogadro’s number and 1 mole? One Mole contains 6.02 x 10^23 particles. Explain how a mole is similar to a dozen. The mole is a unit for counting 6.02 x 10^23 representative particles.
What can be said about 1 mol Ag and 1 mol AU?
Avogadro’s number. What can be said about 1 mol Ag and 1 mol Au? … They contain the same number of atoms.
Which of the following represents the correct relationship between Avogadro number number of particles and mole?
1 mole of molecules = 6.022 × 1023 molecules The number of particles present in 1 mole of any substance is fixed i.e. 6.022 × 1023. This number is called Avogadro constant or Avogadro number. it is represented by No. Relationship between mole, number of particles and mass and interconversion of one into the other.
What is the relationship between a molecule and a mole quizlet?
It’s equal to the number of particles in one mole of a substance. For example, one mole of hydrogen contains 6.022 × 1023 particles of hydrogen. For molecular compounds, like water, the representative particles are molecules.
How many atoms of chlorine are in 1 mole of chlorine gas?
One mole of chlorine weighs 70 grams. Just like a dozen equals twelve, a mole equals Avogadro’s number of atoms or 6.02 × 1023. 6.02 × 1023 molecules of hydrogen would weigh 2 grams. An equal number of chlorine molecules would weigh 70 grams.
Which has more atoms one mole of helium or one mole of lead?
A mole represents Avagadro’s number of particles, and it also represents the quantity of matter in Avagadro’s number, thus providing a transition between the number of particles and the quality of matter. The number of helium atoms in a mole of helium is equal to the number of lead atoms in a mole of lead.
What is the difference between a mole and Avogadro’s number?
The mole allows scientists to calculate the number of elementary entities (usually atoms or molecules ) in a certain mass of a given substance. Avogadro’s number is an absolute number: there are 6.022 × 1023elementary entities in 1 mole.
What is the relationship between a mole of a substance and its mass Brainly?
The mass of one mole of a substance is equal to that substance’s molecular weight. For example, the mean molecular weight of water is 18.015 atomic mass units (amu), so one mole of water weight 18.015 grams.
What is meant by one mole of molecules?
One mole of anything is 6.022×1023 objects of anything. You may recognize 6.022×1023 as Avogadro’s number. One mole of molecules is 6.022×1023 molecules.
Which must be the same when comparing one mole of oxygen gas with one mole of carbon monoxide gas?
Explanation : When comparing 1 mol of oxygen gas with 1 mol of carbon monoxide the number of molecules must be same. Each mole should contains in it. Irrespective of the weight or atomic number avogadro’s number remains constant for every mole of atom.
Why does Avogadro’s law work?
Avogadro’s law states that “equal volumes of all gases, at the same temperature and pressure, have the same number of molecules.” For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant.
