Symbols, abbreviations, or full names for units of length,Īrea, mass, pressure, and other types. You can find metric conversion tables for SI units, as wellĪs English units, currency, and other data. The unit is named after Evangelista Torricelli, Italian physicist and mathematician, for his discovery of the principle of the barometer in 1643.Ĭonversion calculator for all types of measurement units. It is the atmospheric pressure that supports a column of mercury 1 millimetre high. The torr (symbol: Torr) or millimetre of mercury (mmHg) is a non-SI unit of pressure. It is approximately equal to Earth's atmospheric pressure at sea level.
It is sometimes used as a reference pressure or standard pressure. The standard atmosphere (symbol: atm) is a unit of pressure defined as 101325 Pa (1.01325 bar). MmHg to atm, or enter any two units below: Enter two units to convert From: What is the volume at STP?ġ7.You can do the reverse unit conversion from A sample of gas occupies 50.0 L at 15.0 ☌ and 640.0 mm Hg pressure. 500.0 mL of a gas was collected at 20.0 ☌ and 720.0 mm Hg. 73.0 mL of nitrogen at STP is heated to 80.0 ☌ and the volume increase to 4.53 L. If the absolute temperature of a given quantity of gas is doubled and the pressure tripled, what happens to the volume of the gas?ġ5. What will its volume be at 20.0 ☌ and 780. A gas balloon has a volume of 106.0 liters when the temperature is 45.0 ☌ and the pressure is 740.0 mm of mercury.
2.00 liters of hydrogen, originally at 25.0 ☌ and 750.0 mm of mercury, are heated until a volume of 20.0 liters and a pressure of 3.50 atmospheres is reached. What is the volume at STP of 720.0 mL of a gas collected at 20.0 ☌ and 3.00 atm pressure?ġ1. If 10.0 liters of oxygen at STP are heated to 512 ☌, what will be the new volume of gas if the pressure is also increased to 1520.0 mm of mercury?ġ0. Determine the temperature at which the gas will occupy 4250 mL at 1.50 atm.ĩ. A gas sample occupies 3.25 liters at 24.5 ☌ and 1825 mm Hg. What will be the volume of this gas at STP?Ĩ. At a pressure of 780.0 mm Hg and 24.2 ☌, a certain gas has a volume of 350.0 mL. What volume would the same gas occupy when subjected to a pressure of 100.0 atm and temperature of minus245.0 ☌?ħ. 1 mmHg 133.322 pascals (Pa) inHg value x 3386.39 Pa mmHg value x 133.322 Pa inHg value mmHg value x 0.0393701 Alternatively a simpler and more obvious calculation can be used from the known conversion factor for a length measured in millimetres converted to inches: 1 mm 0.0393701 in mmHg value inHg value x 0.
The volume of a gas originally at standard temperature and pressure was recorded as 488.8 mL. What will be the volume of this gas at standard conditions?Ħ. A gas occupies a volume of 34.2 mL at a temperature of 15.0 ☌ and a pressure of 800.0 torr. What will be the volume of the same gas at 745.0 torr and 30.0 ☌?ĥ. At conditions of 785.0 torr of pressure and 15.0 ☌ temperature, a gas occupies a volume of 45.5 mL. What is the volume of gas at 2.00 atm and 200.0 K if its original volume was 300.0 L at 0.250 atm and 400.0 K?Ĥ. What is the final volume of a 400.0 mL gas sample that is subjected to a temperature change from 22.0 ☌ to 30.0 ☌ and a pressure change from 760.0 mm Hg to 360.0 mm Hg?ģ. The 700/760 fraction converts mmHg to atm.ģ. Note that this problem mixes pressure units. When the tank cools to 20.0 ☌, the pressure of the gas is 30.0 atm. The gas is placed into a tank under high pressure. 500.0 liters of a gas are prepared at 700.0 mm Hg and 200.0 ☌. What would the volume of the gas be at 227.0 ☌ and 600.0 torr of pressure?ġ. A gas has a volume of 800.0 mL at minus 23.00 ☌ and 300.0 torr.
