Question

Explain the relationship between mass and mole of a substance​

Answer 1

Answer:

A mole is

6.02

⋅

10

23

(avogadro's number) molecules of a substance. The molar mass is the amount of mass that 1 mole of that substance possesses.

Explanation:

The amount of molecules of any substance to make 1 mole is constant.

However, due to differing atomic masses, different molecules will have different molar masses.

If you have

6.02

feathers and

6.02

⋅

10

23

bricks, you have 1 mole of each, but the bricks have a lot more mass.

• ✏The Mole is specified quantity, $\sf\large{\red{6.02 × 10^{23}}}$. A mole of anything will contain this number of particles, just as a dozen of anything will contain 12. The mass of a mole of particles depends on the mass of the individual particle, just as a dozen golf balls doesn't have the same mass as a dozen ping pong balls.✍

• ✏The molar mass of the substance is the mass of one mole of particles in grams. For example, since the molar mass of carbon is 12 g/mol, one of carbon atoms has a mole of water molecules therefore has a mass of 18g. ✍

• ✏The molar mass is used as a conversion factor to convert grams to moles and moles to grams as follows:

• ✒Mole x molar mass = gram ✍
• ✒Grams/molar mass = moles ✍
