A 256 mL sample of HCl gas is in a flask where it exerts a force (pressure) of 67.5 mmHg. What is the pressure of the gas if it were transferred to a 135 mL flask

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 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

.

answerca air mass;
