Explanation:
The given data is as follows.
= 250 mL,
= 750 mL
=
= 35 + 273 K = 308 K
= 35 + 273 K = 308 K
= 0.55 atm,
= 1.5 atm
P = ? , V = 10.0 L
Since, temperature is constant.
So, = PV
Now, putting the given values into the above formula as follows.
= PV
=
P = 0.126 atm
As, 1 atm = 760 torr. So, = 95.76 torr.
Thus, we can conclude that the final pressure, in torr, of the mixture is 95.76 torr.
Answer:
167.980.
Explanation:
Hello!
In this case, since additions involving the display of the result with the appropriate number of significant figures involve the solution of the system without looking at them:
Considering that 156.325 is significant to the thousandths and 11.65498 to the hundred thousandths, we infer that the result should be taken to the thousandths as well as 156.325; thus, we obtain:
Because the second decimal nine is rounded to ten and therefore the 7 is taken to 8.
Best regards!
