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

Steps to solve this-- Find the percent of increase from 380 to 440. Round to the nearest tenth of a percent if necessary. 13.6%
OLga [1]
If 380 would be 100%

Then use rule of 3

380 ______ 100%

440 ______ y

380y = 440×100%

380y = 440 × 1

Dividing both the sides by 380

y = 440/380

y = 1,158

Let's multiplity "y" by 100

y = 115,8%

As we did have 100% initially

Then the increase will be

The increase = 115,8% -100%

= 15,8%

This would your answer
