<u>Answer:</u> The Henry's law constant for oxygen gas in water is 
<u>Explanation:</u>
To calculate the molar solubility, we use the equation given by Henry's law, which is:
where,
= Henry's constant = ?
= solubility of oxygen gas = 
= partial pressure of oxygen gas = 2.1 atm
Putting values in above equation, we get:
Hence, the Henry's law constant for oxygen gas in water is
It would be 1 or 2 because if the number is higher than 5 you need to round up , if its lower than 5 you need to round down.
