if a gas has a volume of 2.60 L at a pressure of 1.60atm, what will its new volume be at a pressure of 10.6 atm
cricket20 [7]

Answer:

0.39L

Explanation:

Given parameters:

Initial volume of gas V₁ = 2.6L

Initial pressure on gas P₁ = 1.6atm

Final volume of gas V₂ = ?

Final pressure on gas P₂ = 10.6atm

Solution

Applying Boyle's law which states that "the volume of a fixed mass of a gas varies inversely as the pressure changes if the temperature is constant".

Mathematically;

                      P₁V₁ = P₂V₂

                      V₂ = \frac{P_{1}V_{1} }{P_{2} }

                      V₂ =  \frac{1.6 x 2.6 }{10.6 } = 0.39L

At what pressure would 11.1 moles of a gas occupy 44.8 L at 300 K?
faltersainse [42]

Answer:

P=6.10atm

Explanation:

Hello,

In this case, we can study the ideal gas equation that relates temperature, volume, pressure and moles as shown below:

PV=nRT

Thus, since we are asked to compute the pressure y simply solve for it as follows:

P=\frac{nRT}{V}=\frac{11.1mol*0.082\frac{atm*L}{mol*K}*300K}{44.8L}\\  \\P=6.10atm

Best regards.
