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

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
