Answer:
a/b= 2/15
Explanation:
3a +b
----------- = 7/5
b
<h2>now cross multiple both side</h2>
5(3a+b)=7 x b
15a +5b = 7b
15a = 7b-5b
15a = 2b
15a/2b = 1
a/b x 15/2 =1
<h3>multiple both side
by 2/15</h3>
we get,
a/b = 2/15
hope you have no doubt now !
<h2>we get ,</h2>

Answer:
2.82 atm
Explanation:
Initial:
V1 = 28 liters, T1 = 450 C = 450 + 273 K = 723 K, P1 = ?
Final:
V2 = 34 liters, T2 = 350 C = 350 + 273 K = 623 K, P2 = 2.0 atm
Use P1 * V1 / T1 = P2 * V2 / T2
so P1 = P2 * (V2/V1) * (T1/T2) = 2.0 * (34/28) * (723/623) = 2.82 atm
