You should know that electrons have a definite mass. The mass of a body increases a little when it gains electrons. The body mass can also slightly decrease if the body loses electrons during charging.

AICI₃ has greater number of ions, therefore it shows the highest osmotic pressure.

Ph—CH₂-Br will react the fastest by S_N2 mechanism.

Monomer of neoprene polymer is

3-Chloro-1, 3-butadiene

${\pi }_1=iCR{T}_1$

${\pi }_2=iCR{T}_2$            

$\frac{{\pi }_1}{T_1}=\frac{{\pi }_2}{T_2}$            

${\pi }_2=\frac{{\pi }_1*T_2}{T_1}$            

$=\frac{7*10^5*283}{273}$                  

= 7.256 * 10⁵ * Pa

= 72.56 * 10⁴ Pa

p₂ = x * 10⁴

x = 72.56 » 73
