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.
you convert it to g/mole. Think of Mole as the word "dozen." Whenever you see the word "mole" just cross it out and put in the word "dozen". Do the problem like that, and then change all of your dozens to 6^1023. A dozen is 12. A bakers dozen is 13 and a mole is....whatever...some other big number. It doesnt matter. How do you calculate mass of a liquid in grams/dozen? You usese it's atomic weight which is in grams and then convert.
a dozen
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.
No they give mole ratios. A mole is much like a dozen, a dozen is 12 while a mole is 6.02*10^23. This means that 1 mole of a substance represents 6.02*10^23 molecules of that substance.
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.
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).

Try to think of an Avagadro number (1 mole) as being a unit similar to --- say a dozen. 1 dozen eggs has 12 "particles" 1 dozen baseballs has 12 "particles" 1 dozen footballs has 12 "particles" So all three of above have 1 dozen "units". It is the same with an Avagadro number - all with 6.022 x 1023 units. However just as all three examples above have different masses yet all are one dozen. It is the same with an Avagadro number (or 1 mole. ) So 1 mole of hydrogen molecules has a mass of 2g but 1 mole of Uranium atoms has a mass of 238g (because they are much bigger in the same way as a football is bigger than an egg).
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.
The term "mole" is the same as the term "dozen", except that the mole represents a much greater number. Whereas "a dozen eggs" means 12 eggs, "1 mole of eggs" means 6.03x1023 eggs. The reason for using such a large number is that there are typically huge numbers of molecules involved in any chemical reaction in Chemistry.
