3.27 moles of an ideal gas has a pressure of 125000 Pa at 15.0 ° C What is the volume of the gas?

62.86 dm3

Explanation:

Given that:

Volume of water V = ?

Temperature T = 15°C

Convert Celsius to Kelvin

(15°C + 273 = 288K)

Pressure P = 125000 Pa

Convert pressure in Pascal to atmosphere,

If 101,325 Pascal = 1 atm

125000 Pascal = Z

To get Z, cross multiply

Z x 101325 Pa = 125000 Pa x 1 atm

Z = 125000 Pa / 101325 Pa

Z = 1.23 atm

Number of moles of gas = 3.27

Molar gas constant R is a constant with a value of 0.0821 atm dm3 K-1 mol-1

Then, apply ideal gas equation

pV = nRT

1.23atm x V = 3.27 moles x (0.0821 atm dm3 K-1 mol-1 x 288K)

1.23atm x V = 77.32 atm dm3

V = (77.32 atm dm3 / 1.23 atm)

V = 62.86 dm3

Thus, the volume of the gas is 62.86 dm3

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
