Answer:
Pressure gas A
using boyles law
[tex]p1}[/tex][tex]V_{1}[/tex] = [tex]P_{2}[/tex]V2
V2 = 717ml + 179 ml
= 896ml
∴ [tex]P_{2}[/tex] = 2.50 × 717ml/896ml
= 2.0 bar
Pressure B
P2 = 4.30 bar× 179ml/896ml
= 0.859bar
ptotal = [tex]P_{A}[/tex]+[tex]P_{B}[/tex]
= 2.0 bar + 0.859 bar
= 2.859 bar
Explanation: Using Daltons law of partial pressure,the pressure is independently of each other when the gas is exerted.where we can use daltons law to find the pressure of each gas separately when it expands into the total volume in two containers.
