Acylinder is filled with 10.0l of gas and a piston is put into it. the initial pressure of the gas is measured to be 96.0kpa. the piston is now pulled up, expanding the gas, until the gas has a final volume of 45.0l. calculate the final pressure of the gas. be sure your answer has the correct number of significant digits.

The final pressure of the gas is:- 21.3 kPa

Explanation:

Using Boyle's law  

Given ,  

V₁ = 10.0 L

V₂ = 45.0 L

P₁ = 96.0 kPa

P₂ = ?

Using above equation as:

The final pressure of the gas is:- 21.3 kPa

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
