Question

the gas pressure inside an ordinary vacuum chamber is 0.500 torr. calculate the gas pressure in mmhg and atm. round each of your answers to 3 significant digits.

Explanation:

Step1: Convert torr to mmHg

1 torr = 1 mmHg, so 0.500 torr = 0.500 mmHg.

Step2: Convert torr to atm

Use conversion factor 1 atm = 760 torr: $0.500 \times \frac{1}{760} \approx 0.00065789$ atm, round to 3 sig figs.

Answer:

0.500 mmHg, 0.000658 atm
