Use conversion factors from the equivalent pressure units to convert from mmHg to atm and from mmHg to kPa.
This is how many liters of hydrogen gas is needed to react with carbon monoxide to yield 35.7 grams of methanol. Step 1: List the known quantities and plan the problem. 08206 value because it matches all my units.Ħ. 738 mililit thy ngân tng ng vi 0.971053 khí quyn tiêu chun. Plug in your moles, atmospheres, and the temperature in Kelvin. You can use either 8.314 J/Kg*mol or.

Determine the pressure of the gas if the volume is reduced to 321 mL at constant temperature. An 867-mL sample of chlorine gas exerts a pressure of 738 mmHg. This can be interpreted as a 2:1 ratio- we use it to find that 2.228 moles of hydrogen gas are needed to react to produce 1.114 moles of CH3OH.Ĥ. Convert your mmHg to atmospheres using 760 mmHg=1 atm.ĥ. The ideal gas law can be arranged to find volume. Calculate the final pressure if a sample of a certain gas is cooled from 34oC to -73oC, with an initial pressure of 1.45 atm. In this case, for every two moles of hydrogen gas that react, one mole of CH3OH is produced.
To do this, you use the molar mass of CH3OH which is 32.04 grams/mol.ģ. We can now find how much H2 gas is needed by using the molar ratio between it and CH3OH. First, you must convert the target mass of CH3OH to moles. 0.971052632 atm (standard atmosphere) 1.003318237 at (technical atmosphere) 738 torr 10033.183833646 mmH2O (mm of water) 738 mmHg (mm of mercury) 29.055110885 inHg (inches of mercury) 14.270554827 psi (pounds per sq. Given Problem: Methanol (CH3OH) can be synthesized as: CO+2H2→CH3OH. What volume in liters of H2(g) is needed to make 35.7 grams of CH3OH?ġ. We are given the temperature at 355 K and the pressure is 738 mmHg.Ģ.
