I’m pretty sure you would have to divide 5 and 30 and you will get 0.16666666 but I would think it would be 6cm/s but I could be wrong and if it is I’m am truly sorry.
Group 1 contains metals while group 18 contains noble gases.
So group 1 is different from group 18 as they both contains different types of atoms as group 1 contains metals while group 18 contains noble gases.
There is 1 valence shell electron in group 1 , they are highly reactive while valence shell of group 18 is fully filled and they are least reactive .
The answer is:
2.5 moles
The explanation:
when avogadro's number = 6.02 * 10^23
and when 1 mole of the sample will give → 6.02*10^23 atoms
So, ??? mole of the sample will give→ 1.52 x 10^24 atoms
∴ number of moles = (1.52 X 10^24) * 1 mole / (6.02X10^23)
= 2.5 moles
I took the test I think the guy above is correct I’m not to sure good luck thanks
