What term describes how much matter a substances contains?
Mass decribes how much matter a substance contains and Mole decribes the quantity of matter contained in a substance.
Is molar mass is mass in grams of one kilogram of any pure substance?
No, molar mass is the mass in grams of one mole of a substance. One mole is equal to the molecular weight of the substance in grams.
How is a mole related to the atomic mass?
The atomic mass, in grams, is the mass of one mole of atoms.
Which quantity contains Avogadro's number of molecules?
One mole of any substance contains Avogadro's number of molecules, which is approximately (6.022 \times 10^{23}) molecules. This quantity is a fundamental concept in chemistry used to relate the mass of a substance to the number of molecules it contains. For example, one mole of water (H₂O) contains Avogadro's number of water molecules.
How many atoms are present in one gram atomic mass of a substance?
Well, that depends on what substance it is. There's a way to figure it out, though, for every substance. On the periodic table, the atomic mass number for every element is the number of grams in 1 mole of that substance. 1 mole of every substance contains a constant number of representative particles, 6.02x1023. That's called Avogadro's number, and it's the most important constant in chemistry. Given a mass of a substance, it's a simple matter of finding out the number of atoms. For example, let's say you have 80 grams of calcium (Ca). Calcium's atomic mass is 40, and that means 40 grams per mole. You have 80 grams, so that's 2 moles. 1 mole of anything contains 6.02x1023 particles, so that number times your 2 moles get you 1.2x1024 atoms of calcium.
What term describes how much matter a substances contains?
Mass decribes how much matter a substance contains and Mole decribes the quantity of matter contained in a substance.
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.

What is the molar mass of a substance in amu grams per mole?
The molar mass of a substance is the mass of one mole of that substance, measured in atomic mass units (amu) or grams per mole.
What is the SI unit for the amount of a substance that contains as many particles as there are atoms in exactly 12 grams of carbon -12?
mole
What term describes how matter a substance contain?
Mass decribes how much matter a substance contains and Mole decribes the quantity of matter contained in a substance.
How many grams are in one pound-mole (lbmol) of a substance?
One pound-mole (lbmol) of a substance is equal to the molar mass of the substance in grams.
Molar is the total combined mass of a mole of a substance?
mass
What is the molar mass of the substance, expressed in grams per mole (g/mol)?
The molar mass of a substance is the mass of one mole of that substance, expressed in grams per mole (g/mol).
What is a molar mass and how many atoms are in 1 mole of anything?
molar mass is just the moleular mass of an atom or molecule.
How can I convert from pounds mass (lbm) to pounds mole (lbmol) for a given substance?
To convert from pounds mass (lbm) to pounds mole (lbmol) for a substance, you need to know the molar mass of the substance in pounds per mole. Then, divide the given mass in pounds by the molar mass in pounds per mole to get the mass in moles.
What is the molar mass of the substance in amug/mol?
The molar mass of a substance is the mass of one mole of that substance, measured in grams per mole (g/mol) or atomic mass units (amu).
