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 .

<span>1) osmotic pressure exerted by a solution is equal to the molarity multiplied by the absolute temperature and the gas constant r.
Call: P = osmotic pressure; C = molarity; T = absolute temperature
=> P = C * T * r
2) </span><span>write an equation that will let you
calculate the molarity c of this solution. your equation should contain
only symbols. be sure you define each symbol other than r.
</span><span>
</span>=> C = P / (rT)
Answer: C = P / (rT)
Note that
