∙ 16y agoThere are 20 grams in one mole of NE. You have to look at the atomic mass of NE to begin your conversion.
1 mole NE/1 = 20g/1 mole NE
The moles will cancel out, and you're set. All you have to do is multiply.
So basically you just multiply atomic mass by number of moles for any given problem, and that will be your answer. Just keep in mind the number of significant figures!!
I really hope this helps a little bit!!!

How many moles are in 0.125 L of Ne?
0,125 L neon is equivalent to 0,0056 moles.
How many atoms are in 5.5 mol of neon?
Neon is a monatomic gas (1 atom/entity), so finding the number of atoms is as simple as multiplying the quantity of gas by the number of entities in a mole: (5.00 moles Ne gas) (6.022 X 1023 entities/1 mole Ne gas) (1 atom of Ne/entity) = 3.01 X 1024 atoms of Ne ------------------------------------------ You may notice that if the units are treated as factors, they cancel, leaving the desired unit (atoms) at the end.

How do you calculate moles to grams?
Chemical Engineers sometimes measure substance amount in units of gram-moles, kilogram-moles, pound-moles, or ounce-moles; these measure the quantity of a substance whose molecular weight is not equal to its mass in grams, kilograms, pounds, or ounces. The SI mole is identical to the gram-mole. This is from wikipedia entry on moles. So 1 mole = 1 gram-mole
How many protons in 20.02 moles of neon?
The first step is to identify what you have and what you need. The units of our data is grams. The units that we desire is number of atoms. Therefor, to answer this question, we need two important tools of chemistry: the periodic table, where we can find the molar mass of the element (bottom of the element's box), and Avogadro's number, which is the number of atoms in one mole.Going to our periodic table, we find the molar mass to beM=20.1797 grams/moleand Avogadro's number isNA=6.022*1023 atoms/moleTo make the conversion, we simply track our units through the calculation:80 grams of Ne * 1 mole Ne/20.1797 grams Ne * 6.022*1023 atoms Ne/mole Ne=2.39*1024 atoms NeIt is worth noting that any conversion factor can be reversed by reciprocating the value. In the above example, the molecular mass is given in grams per mole, which can be used to convert moles to grams. The reciprocal was used to convert grams into moles.
How many atoms of neon gas are present in 0.251 mol of Ne?
