Answer:
The answer to your question is 2.52 moles
Explanation:
Data
Volume = 60.5 l
Temperature = 20°C
Pressure = 1 atm
Constant of ideal gases = R = 0.082 atm l/mol°K
Formula
PV = nRT
-Solve for n
n = PV / RT
-Convert temperature to °K
Temperature = 20 + 273
= 293°K
-Substitution
n = (1 x 60.5) / (0.082 x 293)
-Simplification
n = 60.5 / 24.026
-Result
n = 2.52 moles
The phrase 1 meter per second is a unit of velocity and is a unit of rate. 1 meter per second means for every second, for example, a man runs, he travels 1 meter distance. 1 meter per second is a derivative of the primary units of SI system, meter for distance and second for time.
