A vertical cylindrical tank contains 1.80 mol of an ideal gas under a pressure of 0.300 atm at 20.0°C. The round part of the tan
frez [133]

Answer:

Part A m = 97.37 Kg

Part B H = 4.59 meters

Explanation:

Part A

Pressure is equal to force per unit area

P = \frac{F}{A}

Here force is equal to the weight of the piston

Thus

P = \frac{m*g}{A}

On rearranging the equation, we get -

m = \frac{PA}{g} \\m = \frac{P\pi r^2}{g}

Substituting the given values we get

m = \frac{0.3*1.013*10^5*0.1^2}{9.8} \\m = 97.37

Part B

We know that

V = \pi r^2h\\

On substituting the given values we get -

pV = nRT\\V = \frac{nRT}{p}

V = \frac{1.8*8.314*293}{0.3039*10^5} \\V = 0.1442 m^3

Height

= \frac{V}{\pi r^2} \\= \frac{0.1442}{\pi 0.1^2} \\= 4.59
