the mole, pair & dozen are all units which denote a particular number of objects.
30 dozen pairs = 30 * 12 * 2 = 720 individual gloves.
Thirty dozen is 30x12=360 gloves. Each individual gets two gloves so 360/2=180 people would have pair of gloves. This assumes all individuals have to hands.Alternately. 30 dozen gloves is 30/2=15 dozen pairs of gloves or 15x12=180 pairs. 1 pair per person meets the needs of 180 people.
Yes, the word 'dozen' is a noun, a singular, common noun; a word for twelve of something, a thing.
Yes, word dozen is a noun, a singular common noun; a word for a quantity or a number, a thing.

Mole is not a unit of volume. Mole deals with numbers like dozen.
6.02 x 1023I think it should rather be: A dozen is to twelve as a mole is to 6.02 x 1023.
To calculate the mass of an unknown liquid in grams per mole, you would need to know the substance's molar mass (g/mol) and the amount of the substance in grams. Then, divide the mass in grams by the molar mass to get the value in grams per mole.

A mole is just a number, like a dozen, but a lot bigger. So the question is like asking "Does a box of a dozen small eggs have the same number of eggs as a box of a dozen jumbo eggs?" (Yes, they both have a dozen, 12, eggs. They both have Avogadro's number of molecules.) Trick question: a mole is a count of molecules, not atoms. A mole of water would have half again as many ATOMs as a mole of oxygen, since water comes 3 atoms to the molecule, but oxygen as O2 has 2 atoms per molecule. Similarly a dozen breakfasts of 3-egg omelets would have half again as many eggs as a dozen breakfasts of 2 fried eggs.
Mole is a unit of quantity, just like a dozen is a unit of quantity. So you cant say a mole equals this many pounds because it will matter of what it is you are measuring. A dozen apples weighs less than a dozen elephants, the same can be said for moles.
Carbon atoms would weigh more because they have six protons and six neutrons. The most common form of Hydrogen has one proton and no neutrons, which means that Carbon is normally about 12 times as heavy as Hydrogen (in their most common forms).
A mole is analogous to a dozen in that it represents a specific quantity, like 12. A mile is analogous to a kilogram or a pound as it represents a unit of distance. A fluid ounce is analogous to a milliliter as they both measure volume. A degree is analogous to a radian as they both measure angles.
The number of any item in a mole is equal to Avogadro's number, or 6.0221415 × 10^23 items. So, in the case of O2, it would be 6.0221415 × 10^23 O2 molecules. It's like asking how many eggs in a dozen versus how many marbles in a dozen, no matter what you're talking about, a dozen is 12. Same thing for moles.
Yes, coefficient balanced equations in chemistry provide the relative amounts of substances involved in a chemical reaction by indicating the mole ratios. These mole ratios can then be used to establish mass-to-mass relationships by converting between moles and masses of the substances involved in the reaction.
the answer is there number of atoms
A mole represents a number of Avogadro's Constant. It is same as naming 12 units a dozen. It is not related with the weight of atoms, molecules, ions or compounds.
