One mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions). The number 6.022 × 10²³ is known as Avogadro's number or Avogadro's constant. The concept of the mole can be used to convert between mass and number of particles.

Answer:
Even small amounts of radiation over a prolonged period of time can be dangerous.
Explanation:
We all get exposed to radiation, such as through x-rays, and it's fine as one off experiences. However, if you're constantly dealing with radiation without any sort of protection, no matter how small the amount is, it could potentially lead to consequences like cancer. This is due to the fact that radiation can alter our genes
The question is incomplete. The complete question is:
The partial pressure of 
in your lungs varies from 25 mm Hg to 40 mm Hg. What mass of can dissolve in 1.0 L of water at 25 degree Celsius if the partial pressure of is 40 mm Hg.
Answer: 
Explanation:
Henry's law states that the amount of gas dissolved or molar solubility of gas is directly proportional to the partial pressure of the liquid.
To calculate the molar solubility, we use the equation given by Henry's law, which is:
where,
= Henry's constant = 
= partial pressure = 39 mm Hg = 0.051 atm (760mmHg=1atm)
Putting values in above equation, we get:
Hence, of can dissolve in 1.0 L of water at 25 °C if the partial pressure of is 39 mm Hg
