Question

the pressure inside a gas cylinder is 3,506 mmhg. how many atmospheres of pressure is the gas exerting on the cylinder?

0.2168 atm
4.613 atm
34.60 atm
467.4 atm

Explanation:

Identify the conversion factor between mmHg and atm

$$ 1\text{ atm} = 760\text{ mmHg} $$

Convert the given pressure to atmospheres

$$ P = \frac{3506\text{ mmHg}}{760\text{ mmHg/atm}} \approx 4.61315789\text{ atm} $$

Match with the correct option

$$ P \approx 4.613\text{ atm} $$

Answer:

• (A) 0.2168 atm
• (B) 4.613 atm (Correct answer)
• (C) 34.60 atm
• (D) 467.4 atm
