Volume in mL of 1 mole H2(g) at STP =(1molex ~ mLH2(g)producedat STP) ~ ofmolesH2(g) produced (5 points) 7. Using the volume in mL of H2(g) produced at STP, convert mL H2(g) to L H2(g). 1 L = 1 000 mL L H2(g) = #mLH2(g) x1 L___ 1 000mL ...
Molar Mass of a Gas:We are familiar with the pressure (P), volume (V), temperature (T), and number of moles (n) of gas in the Ideal Gas Law equation but the molar mass of the gas can also be calculated from the same equation. Like any other calculati...
which is 0.008 mol. From there we were able to determine the volume of oxygen by looking up the water vapor pressure at the recorded temperature, and subtracting that from the current barometric pressure to give the pressure in torr for oxygen (739.3 torr), then utilized the state of gas ...
What is the molar mass of 54g of oxygen? What is the molar mass of acetic acid? A solution of nitric acid HNO3 is prepared by dissolving 2g of the gas HNO3 into 500mL of water. What is the pH of the solution? What is the molar mass of Al(OH)3?

Here, the Ea value is higher than ∆H◦, indicating a cathodic hydrogen evolution reaction leading to a decrease in total reaction volume. The average value of Ea–∆H◦ is 2.58 kJ mol−1, which is very close to the value of RT; this obeys the relation Ea–∆H◦ = RT. ...
From these results, it can be concluded that primary tribochemical processes dominate over secondary radical processes that involve atmospheric oxygen and subsequent radical reactions. Furthermore, Fujimoto et al. [14] introduced the yield of 'extractable lignin' determined by a 96% dioxane extraction...

The mixture was stirred overnight, and the resulting product was precipitated by tripling the volume with the addition of anhydrous ethanol, before being separated by centrifugation. The solid material was heated at 723 K for 1 h in air to remove the surface capping agents, and was then ...
