What is the pressure of 0.0525 moles of an ideal gas whose volume is 3.5 L and temperature is 298 K? Answer:

A cylinder filled with CO2 is often used to carbonate fizzy drinks. After some use, the pressure of the cylinder was 113400 pa. If the volume of the cylinder is 60.00L and temperature is 297.0K, what is the mass of carbon dioxide remaining? Answer to appropriate number of significant figures.

To what temperature in K must a variable volume container of helium gas be cooled to obtain a final volume of 0.255 L? The initial volume and temperature are 2.86 L and 332 K, respectively. The pressure and number of moles are fixed. of Answer:

at what temperature does 2.39g of H2 gas occupy a volume of 65.5L at a pressure of 1.06 atm? Answer in Celsius

QUESTION 4 Determine the density of SO 2(g) at a pressure and temperature of 0.5846 atm and 283.4 K, respectively. Key Concept:Density equation for gases comes from the ideal gas law. d = P*MW/R*T. Substitute into density equation

What is the volume occupied by 0.398 moles of di-oxygen gas at a pressure of 2.48 atm and a temperature of 465 K (ideal gas)? What is the volume occupied by 0.398 moles of di-oxygen gas at a pressure of 2.48 atm and a temperature of 105 K (van der Waals gas):

You have a gas sample of carbon dioxide at 298 K. If the pressure is 0.827 atm what is the pressure of your gas sample in mmHg ?   Answer using dimensional analysis
