Answer:
The pressure in the new flask would be if the
here acts like an ideal gas.
Explanation:
Assume that the sample here acts like an ideal gas. By Boyle's Law, the pressure
of the gas should be inversely proportional to its volume
.
For example, let the initial volume and pressure of the sample be and
. The new volume
and pressure
of this sample shall satisfy the equation:
.
In this question,
- The initial volume of the gas is
.
- The initial pressure of the gas is
.
- The new volume of the gas is
.
The goal is to find the new pressure of this gas, .
Assume that this sample is indeed an ideal gas. Then the equation should still hold. Rearrange the equation to separate the unknown,
. Note: make sure that the units for
and
are the same before evaluating. That way, the unit of
.
