What is a characteristic of 1 mole of gas at STP?
The volume is 22,710 980(38) litres for the ideal gas.
Assume you fill a 22.4 liter balloon with helium gas how much would the gas inside weigh?
The weight of the helium gas inside the balloon can be calculated using its molar mass, the Ideal Gas Law, and the given volume. Assuming standard conditions, helium gas has a molar mass of 4 grams per mole. Thus, a 22.4 liter balloon filled with helium gas would weigh approximately 32 grams.
What is the ideal gas contact?
The ideal gas constant has different values depending on the units one uses for pressure. Thus, if using atmospheres, R = 0.0821 L-atm/K-mole. If using kPa, R = 8.314 L-kPa/K-mole, and if using mm Hg, R = 62.36 L-mm Hg/K-mole.
How much volume does 1 mole of a gas occupy at NTP?
At NTP (standard temperature and pressure), 1 mole of any ideal gas occupies approximately 22.4 liters of volume.
What is the molecular mass of ether?
I will assume the ether behaves as an ideal gas. In that case, a mole (gram molecular weight) of the gas occupies 22.4 liters at STP. If 3.96 liters weigh 8.12 grams, then 22.4 liters weighs x where: 8.12/3.96 = x/22.4 Turn the crank, and 22.4 liters of ether weigh 45.9 grams, the gram molecular weight of ether.
