A gas occupies 3.5L at 2.5 kPa pressure. What is the volume at 100 mmHg at the same temperature? Be sure to
nasty-shy [4]

The volume at 100 mmHg : 0.656 L

<h3>Further explanation</h3>

Boyle's Law  

<em>At a constant temperature, the gas volume is inversely proportional to the pressure applied  </em>

\rm p_1V_1=p_2.V_2\\\\\dfrac{p_1}{p_2}=\dfrac{V_2}{V_1}

V₁=3.5 L

P₁=2.5 kPa=18,7515 mmHg

P₂=100 mmHg

\tt \dfrac{18.7515}{100}=\dfrac{V_2}{3.5}\\\\V_2=\dfrac{18.7515\times 3.5}{100}=0.656~L

alex41 [277]

Explanation:

c.

from \\  \frac{P _{1} V _{1} }{T _{1}}  =  \frac{P _{2} V _{2}}{T _{2}} \\ \frac{2 \times 75}{(10+273)}  =  \frac{V _{2} \times 1}{(35+273)}  \\V _{2} =  \frac{2 \times 75 \times (35+273)}{(10+273) \times 1}   \\ V _{2} = 163 \: ml
