If both temperature and volume of an ideal gas are halved, how does the pressure change? A gas at STP is heated to 819 K. What is the new pressure in atm? Calculate the molar mass of a gas if its density is 3.67 g/L at 15.0 degrees Celsius and 825 torr. ...
Understand the definition of mole ratio, how to find mole ratio in stoichiometry, and see examples of using mole ratio in problems. Related to this QuestionHow many liters of H2 gas can be produced at 0 deg C and 1.00 atm (ST...
The gas law which relates the volume of a gas to moles of the gas is: View Solution What is the relation between the activity of a gaseous component and its partial pressure ? View Solution Heat required to raise the temperature of 1 mole of a substance by1∘C is called ...
the terms low and high are relative terms, meaning that system has either lower or higher barometric pressure than the surrounding areas. Many barometers use mercury to measure barometric
