The gas pressure inside a high vacuum chamber is 0.000000132atm. Calculate the gas pressure in mmHg and torr. Round each of your answers to 3 significant digits.

0.000000132 atm is  0.000100 mm Hg = 0.000100 torr

Explanation:

Step 1: Data given

Pressure in atmosphere = 0.000000132atm

1 atm = 760 mm Hg

1 torr = 1 mmHg

1 atm = 760 torr

Step 2: Calculate the pressure in torr and mmHg

1 atm = 760 mmHg

0.000000132atm = 760 * 0.000000132 mm Hg

0.000000132atm = 0.00010032 mm Hg

Since 1 torr = 1 mmHg

0.00010032 mm Hg =  0.00010032 torr

Step 3: convert to 3 significant digits

0.00010032 ⇒ 0.000100 mm Hg = 0.000100 torr

0.000000132 atm is  0.000100 mm Hg = 0.000100 torr

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
