Answer:

Option C. 0.7x10^2 moles

Step-by-step explanation:

1mole of a substance contains 6.02x10^23 atoms as discovered from Avogadro's hypothesis.

If 1 mole of Ne contains 6.02x10^23 atoms,

Therefore, Xmol of Ne will contain 4.2154x10^25 atoms i.e

Xmol of Ne = (4.2154x10^25)/6.02x10^23 = 70moles = 0.7x10^2 moles

What's bigger 2/3 or 4/5
Eduardwww [97]
The best thing to do is either to find a common denominator or convert them to decimals.
I will find a common denominator.
A common denominator of 3 and 5 is 15.
You multiply the first fraction by 5
2*5= 10
This then becomes 10/15
You then multiply the second by 3.
4*3= 12
Therefore, this becomes 12/15
As the second of these fractions is larger, this means that 4/5 is larger.
The alternative method is to put them into decimals, in which case 2/3= 0.66 and 4/5= 0.8
Hope this helps :)
