what mass, in grams, of oxygen gas (o2) is contained in a 10.5-liter tank at 27.3 degrees celsius and 1.83 atmospheres? show all of the work used to solve this problem.

Answer : The mass of oxygen gas contained in the tank is 24.9 grams.

Explanation :

Using ideal gas equation:

where,

P = pressure of oxygen gas = 1.83 atm

T = temperature of oxygen gas =

V = volume of oxygen gas = 10.5 L

M = molar mass of oxygen gas = 32 g/mole

w = mass of oxygen gas = ?

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

Now put all the given values in the above equation, we get:

Therefore, the mass of oxygen gas contained in the tank is 24.9 grams.

is it a purebred? it looks more like a red nose, but it doesn't have the red could it be a staffordshire bull terrior? unsure if that's the right name for it sorry
