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

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

lol idk man i guess u gotta ask bill nye the science guy
