Answer:
The gas pressure in both mmHg and torr is 1.00 x10⁻⁴.
Explanation:
The standard atmosphere (1 atm) equals a pressure of 760 mmHg, where mmHg represents the pressure exerted by a column of mercury 1 mm high. The mmHg unit is also called the torr, after the Italian scientist Evangelista Torricelli, who invented the barometer. Thus,
1 torr = 1 mmHg
and
1 atm = 760 mmHg = 760 torr
Therefore, we do the following conversion:
1 atm ------------------- 760 mmHg
1.32x10⁻⁷ atm ------- x= 1.00 x10⁻⁴ mmHg (3 significant digits)
Answer:
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
