Answer:
P = 3,63 atm
Explanation:
Using PV=nRT and knowing the temperature in the problem remains constant it is possible to rewrite this formula, thus:
PV = kn, where k is RT (Constant), P is pressure, V is volume and n are moles.
The first bulb contains:
4,87L×4,38atm = 21,3k moles
And the second bulb:
4,87L×2,90atm = 14,1k moles
When gases are mixed, the total moles are:
21,3k moles + 14,1k moles = <em>35,4k moles</em>
As total volume is 4,87L + 4,87L = <em>9,74L</em>
Replacing:
P = kn/V
P = 35,4k moles / 9,74L
<em>P = 3,63 atm</em>
<em></em>
I hope it helps!
