Question

a gas has a volume of 55mL and a pressure of 130 atm. what is the pressure of the gas if the volume changes to 100ml?

Answer 1

71.5 atm

Step-by-step explanation:

Use Boyle's Law and rearrange formula.

Answer 2

`\large \boxed{\text{71.5 atm}}`

Step-by-step explanation:

The only variables are the pressure and the volume, so we can use Boyle's Law.

Data:

p₁ = 130 atm; V₁ = 55 mL

p₂ = ?; V₂ = 100 mL

Calculation:

`\begin{array}{rcl}p_(1)V_(1) & = & p_(2)V_(2)\\\text{130 atm} * \text{55 mL} & = & p_(2) *\text{100 mL}\\\text{7150 atm} & = & 100p_(2)\\p_(2) & = & \frac{\text{7150 atm}}{100}\\\\& = &\textbf{71.5 atm}\\\end{array}\\\text{The new pressure of the gas is $\large \boxed{\textbf{71.5 atm}}$}`
