Answer:
2.1 atm
Explanation:
The new pressure can be found by using the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
Since we are finding the new pressure
[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]
From the question we have
[tex]P_2 = \frac{3.5 \times1.2 }{2} = \frac{4.2}{2} \\ [/tex]
We have the final answer as
2.1 atm
Hope this helps you
