WebIs 1 atm exactly 760 mmHg? Yes, 1 standard atmosphere (atm) is exactly equal to 760 millimeters of mercury (mmHg). Is atm greater than mmHg? Yes, one standard atmosphere (atm) is greater than one millimeter of mercury (mmHg). There are 760 mmHg in a standard atmosphere but only 0.0013157894736842 standard atmospheres (atm) in one mmHg. WebJan 18, 2024 · Moles = (Pressure × Volume) / (0.0821 × Temperature) If you want to work it out yourself, without the molar mass of gas calculator, be careful with the units! This particular equation uses a constant of 0.0821, …

WebIt is denoted mmHg or mm Hg. Although not an SI unit, the millimetre of mercury is still routinely used in medicine, meteorology, aviation, and many other scientific fields. One millimetre of mercury is approximately 1 Torr, which is 1 / 760 of standard atmospheric pressure (101 325 / 760 ≈ 133.322 368 pascals). WebThe pressure on the left is due to the gas and the pressure on the right is due to 13.7 cm of Hg plus atmospheric pressure.) (a) In mm Hg, this is: 137 mm Hg + 760 mm Hg = 897 mm Hg (b) 897 mm Hg × 1 atm 760 mm Hg = 1.18 atm (c) 1.18 atm × 101.325 kPa 1 atm = 1.20 × 10 2 kPa Check Your Learning WebA pressure of 1 atm can also be stated as: ≡ 101 325 pascals (Pa) ≡ 1.013 25 bar ≈ 1.033 kgf /cm 2 ≈ 1.033 technical atmosphere ≈ 10.33 m H 2 O, 4 °C [n 1] ≈ 760 mmHg, 0 °C, subject to revision as more precise measurements of mercury's density become available [n 1] [n 2] ≡ 760 torr (Torr) [n 3] sustained shared thinking youtube
