Answer:
Molar mass of bromine is equal to
Explanation:
The molar mass of HBr is equal to the sum of atomic weight of Bromine.
Atomic Weight of hydrogen is equal to
Atomic Weight of Bromine is equal to
Molar mass of Bromine
= Atomic Weight of hydrogen + Atomic Weight of Bromine
Molar mass of Bromine
At a particular temperature, the solubility of He in water is 0.080 M when the partial pressure is 1.7 atm. 4.25 atm is the partial pressure of He would give a solubility of 0.200 M.
<h3>What is Henry's Law ?</h3>Henry's Law is a gas law states that at a constant temperature the amount of gas that dissolved in a liquid is directly proportional to the partial pressure of that gas.
<h3>What is relationship between Henry's Law constant and Solubility ?</h3>The solubility of gas is directly proportional to partial pressure.
It is expressed as:
where,
= Solubility of gas
= Henry's Law constant
= Partial pressure of gas
Now put the values in above expression we get
0.080M = × 1.7 atm
= 0.047 M/atm
Now we have to find the partial pressure of He
0.200 M = 0.047 M/atm ×
= 4.25 atm
Thus from the above conclusion we can say that At a particular temperature, the solubility of He in water is 0.080 M when the partial pressure is 1.7 atm. 4.25 atm is the partial pressure of He would give a solubility of 0.200 M.
