Air is basically 80% of nitrogen and 20% of oxygen. a 2.0 mol sample of air is found to occupy 6.0l at 27%. what is the partial pressure of oxygen in the sample?

Explanation:

1. Moles of O₂  

2. Partial pressure of O₂

To calculate the partial pressure of the oxygen, we can use the Ideal Gas Law:

pV = nRT

Data:

V = 6.0 L

n = 0.40 mol

T = 27 °C

Calculations:

T = (27 + 273.15) K = 300.15 K

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
