The Determining the Molar Volume of a Gas Classic Lab Kit for AP® Chemistry involves determining the volume of one mole of hydrogen gas at standard temperature and pressure (STP). A water displacement technique yields hydrogen for analysis. See more product details Product Details ...
What volume (in liters) of oxygen must react to form 17.0 L of carbon dioxide according to the following balanced equation: 2CO(g) + O_2(g) \to 2CO_2(g)? What is the volume of oxygen gas at STP from the decomposition of 10.8 g of mercuric oxide?
What volume of oxygen must be available at STP to allow 6 g of hydrogen gas to react and form water?Balanced Chemical Equations:A balanced chemical equation is a type of expression for the chemical change that is quite helpful in computations. The coefficie...
To find the volume of Cl₂ produced at STP by the action of 100 cm³ of 0.2N HCl on excess MnO₂, we can follow these steps:Step 1: Write the balanced chemical equation The reaction between MnO₂ and HCl can be represen
Step 1: Understand the meaning of '30 volume''30 volume' hydrogen peroxide means that 1 liter of this solution will produce 30 liters of oxygen gas (O₂) at standard temperature and pressure (STP).Step 2: Write the balanced chemical equationThe...
Calculate the pressure in bar of 2520 moles of hydrogen gas stored at 27 °C in the 180-L storage tank of a modern hydrogen-powered car. Show Answer If the number of moles of an ideal gas are kept constant under two different sets of conditions, a useful mathemati...

Engineers and scientists typically refer to tables of specific volume values. These representative values are for standard temperature and pressure (STP), which is a temperature of 0 °C (273.15 K, 32 °F) and pressure of 1 atm. Substances marked with an asterisk (*) are not at STP. ...
This was done by crushing the coal in the high-vacuum inlet system of a research mass spectrometer. The gases observed were composed of C, S, H, O, N, He and Ar atoms. Water was the most abundant gas; others were hydrogen, helium, methane, ammonia, methanol, ethanol, carbon monoxide...
