6.022 x 1023 molecules are in a mole. 12 molecules are in a dozen. 6.022 x 1023 atoms are in a mole. 12 atoms are in a dozen. 6.022 x 1023 eggs are in a mole. 12 eggs are in a dozen. A mole is like a dozen. I hope the examples above explain the concept. You may message me if you need any further clarification.

1 of them.

Always there are 6.02*1023 particles in ONE mole:(very much the same as: How many WhatSoEver in a dozen (12) or gross (144)In 0.25 moles = 0.25*6.02*1023 = 1.5*1023molecules O2

Dozen is twelve. So it would be 12 stamps in a dozen.

There are 6.022 x 1023 elementary particles in a mole. If you had a mole of Hydrogen atoms you would have 6.022 x 1023 electrons. If you had mole of Neon you would have 6.022 x 1023 electrons. etc

There would be 12. 12 is a dozen

18 dozen x 12 per dozen = 216

12 roses would make a dozen, so 12 roses times 60 dozen is equal to 12x60, which would be 720

3 dozen would be 36 cookies, unless it is a bakers dozen in which case your total would be 39 cookies.

One dozen equals 12 (items). 6 is one half (1/2) of a dozen. So 6 stars would be one-half dozen if you need how many dozens.

A gross (a dozen dozen) is equal to 144. Therefore you would have 432 pencils.

There are: (1023*24)/12 = 2046

Answer: 1023 km = 635.662 mi

Saying that you have 2.0 moles of He is like saying that you have 2 dozen of something. We all know a dozen to be equal to 12, and in this case, the "dozen" is Avogadro's number (6.022*1023). If you multiply 2 dozen by 12, you'll have the number of whatever you're counting (24), and if you multiply 2.0 moles of He by Avogadro's number, you'll have the number of He atoms you're talking about.

One mole of anything is approximately 6.022 x 1023 units. So, one mole of Ba would be 6.022 x 1023 atoms. One mole of H would be 6.022 x 1023. And so forth...

1023 km = approx 636 miles.

It depends on the molecule. I mole of contains 6.022 x 1023 molecules. So if the molecule was Mg which is also an atom - there would be Mg 6.022 x 1023 If the molecule was H2 then there would be 6.022 x 1023 x 2 = 1.2044 x 1024 If the molcule was H2O then there would be 6.022 x 1023 x 3 = 1.8066 x 1024 If the molcule was H2O2 then there would be 6.022 x 1023 x 4 = 2.4088 x 1024 etc.

That would be 12. A dozen is always 12, regardless of what is being counted.

A mole of hydrogen would contain as many atoms as a mole of lead. Mole has a definite quantitative meaning, rather like a dozen does. A mole is, 6.022 X 1023 atoms per elemental mass.

A dozen means 12. Thus, 8 Dozen eggs would mean, 8 X 12 = 96 eggs.

12 items make up a dozenfor example if u have 12 eggs u would have a dozen or if u had 6 eggs u would have a half-dozen because 6 is half of 12

One mole is 6.02 Ã— 1023 molecules. So 2 molecules out of that 6.02 Ã— 1023 would be 2/(6.02 Ã— 1023) or 3.32 Ã—10-24 moles.
