According to Dalton's law, overall pressure is equal to the sum of the partial pressures of individual gases. The three samples exert 2220 mm Hg pressure.
The overall pressure exerted by a mixture of gases, according to Dalton's law of partial pressures, is equal to the sum of the partial pressures of all existent individual gases, and each gas is considered to be an Ideal gas.
According to dalton's law of partial pressure,
[tex]P_{total} = P_1+P_2+P_3[/tex]
The partial pressures of gases 1,2 and 3 are P1, P2, and P3, respectively
Given,
[tex]\rm{P_1=P_2=P_3}=740 \;mm\rm \;Hg[/tex]
On putting all the values
[tex]P_{total} = P_1+P_2+P_3[/tex]
[tex]\rm P_ {total} &=( \rm{740+740+740} ) \;\rm mm\;Hg\\\\\rm P_ {total} &=2220 \;\rm mm\;Hg\end{aligned}[/tex]
Hence the three samples exert 2220 mm Hg pressure when kept in a single 2 L container.
