Carbon dioxide gas is collected at 27.0(degrees)c in an evacuated flask with a measured volume of 30.0l. when all the gas has been collected, the pressure in the flask is measured to be 0.480atm.

calculate the mass and number of moles of carbon dioxide gas that were collected. round your answer to 3 significant digits.

Moles of carbon dioxide gas is 0.584 moles.

Mass of 0.584 moles of carbon dioxide gas is 25.7  g

Explanation:

Using ideal gas equation

PV = nRT

where,

P = Pressure of gas =

V = Volume of gas = 30.0 L

n = number of moles of gas = ?

R = Gas constant = 0.0821 L.atm/mol.K

T = Temperature of gas = 27°C = 300.15 K

Putting values in above equation, we get:

Moles of carbon dioxide gas = 0.584 moles

Mass of 0.584 moles of carbon dioxide gas = 0.584 mol × 44 g/mol = 25.69 g ≈ 25.7  g

some of the qualities most frequently associated with the baroque are grandeur, sensuous richness, drama, vitality, movement, tension, emotional exuberance, and a tendency to blur distinctions between the various arts.

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
