Answer:
T = 246 K
Explanation:
Given that,
Number of moles, n = 0.750 mol
The volume of the cylinder, V = 6850 mL = 6.85 L
Pressure of the gas, P = 2.21 atm
We need to find the temperature of the gas stored in the cylinder. We know that,
PV= nRT
Where
R is gas constant
T is temperature
So,

or
T = 246 K
So, the temperature of the gas is equal to 246 K.
Viscosity refers to a fuilds resistance to flow.
EX: Honey have higher viscosity than water.
