Answer:
135.9 atm
Step-by-step explanation:
Same question on my chemistry hw
The pressure of the gas is 140 atm up to two significant figure
We have given that,
[tex]P1 = 88.89 atm[/tex]
[tex]V1 = 17L[/tex]
[tex]V2 = 12 L[/tex]
We have to find,[tex]P2 = ?[/tex]
The application of the ideal gas law in the form of,
[tex](P1V1)/T1 = (P2V2)/T2[/tex]
We have to find P2
Therefore, rearrange the equation to the form of
[tex]\frac{(P_1V_1T_2)}{(T_1V_2)} = P_2[/tex].......(1)
we have to convert your temperatures from Celsius to K by adding 273 to each.
So we get,
[tex]T1 = 67 +273 = 340 K[/tex]
[tex]T2 = 94 + 273 = 367[/tex]
[tex]P2 = ?[/tex]
By using equation (1) we get,
[tex]P_2=\frac{(88.89*17*367)}{(340*12)} \\\\p_2=\frac{623213.71}{4080}\\p_2=139.26\\p_2=140 up to two significant figure.[/tex]
Therefore,the pressure of the gas is 140 atm up to two significant figure
