# Question 17ce4

Aug 26, 2016

$\textcolor{m a \ge n t a}{\text{50 mL}}$

#### Explanation:

This question requires you to use Charles' law:

${V}_{1} / {T}_{1} = {V}_{2} / {T}_{2}$

The number 1 represents the initial conditions and the number 2 represents the final conditions.

Identify your known and unknown variables:

color(red)("Knowns:"

${V}_{1}$= 25 mL
${T}_{1}$= 300K
${T}_{2}$ = 600K

color(magenta) ("Unknowns:"#

${V}_{2}$

Rearrange the equation to solve for ${V}_{2}$

${V}_{2} = \frac{{V}_{1} \times {T}_{2}}{T} _ 1$

Plug in your given values to obtain the final volume:

${V}_{2} = \frac{25 m L \times 600 \cancel{K}}{300 \cancel{K}}$ = $50 m L$
