Question

A gas has a pressure of 1.43 atm and occupies

a volume of 7.7 L. If the gas is compressed to
a volume of 1.64 L, what will its pressure be,
assuming constant temperature?

Answer 1

Step-by-step explanation:

The pressure of a gas can be calculated using the ideal gas law, which states that PV = nRT, where P is the pressure, V is the volume, n is the number of moles of gas, R is the ideal gas constant, and T is the temperature in kelvin.

Assuming that the number of moles of gas and the temperature remain constant during the compression, the pressure of the gas after compression can be calculated as follows:

P2 = (nRT) / V2 = (nRT) / 1.64 L

where P2 is the pressure after compression and V2 is the volume after compression. To find P2, we need to substitute the known values into the equation:

P2 = (1.43 atm * 7.7 L) / 1.64 L = 6.76 atm

So, the pressure of the gas after compression will be 6.76 atm.
