Question

A 10.0 L sample of gas has a pressure of the 1.00 atm. If the volume increases to 15.0 L, what is the pressure of the gas ? Assume constant temperature.
Please help thanks.

Answer 1

Answer:

0.67 atm

Explanation:

From the question,

Applying Boyles law

PV = P'V'......................... Equation 1

Where P = Initial Pressure of the sample of gas, P' = Final pressure of the sample of gas, V = Initial volume of the sample of gas, V' = Final volume of the sample of gas.

make P' the subject of the equation above

P' = PV/V'.................... Equation 2

Given: P = 10.0 L, V = 1.0 atm, V' = 15.0 L

Substitute these values into equation 2

P' = (10.0×1.0)/15.0

P' = 0.67 atm
