We are given with
V = 12L
T = 298 K
P = 1000 kPa
We are asked to get the number of moles, n
We can solve this using the ideal gas law
PV = nRT
n = PV / RT
Simply substitute the values and use the appropriate value for R.
21/4 * 4 * 2/3
21 * 2/3
42/3 = 14
Answer:
C.
Explanation:
A gas can expand to fill any volume and takes the shape of the container.
