Answer:
0.33L
Explanation:
From ideal gas equation,
PV = nRT
V = nRT/P
If RT/P are kept constant, then:
V1/n1 = V2 /n2
n1 = 1.5moles
V1 = 0.25L
n2 = 1.5 + 0.5 = 2moles
V2 =?
Now, the new volume can be obtain as follows:
V1/n1 = V2 /n2
0.25/1.5 = V2/2
Cross multiply to express in linear form
1.5 x V2 = 0.25 x 2
Divide both side by 1.5
V2 = (0.25 x 2)/1.5
V2 = 0.33L
Therefore, the new volume is 0.33L
