Answer : The solubility is, 
Explanation : Given,
= Henry's law constant of argon = 
First we have to calculate the pressure of argon.
Pressure of argon = 
Pressure of argon = 0.0093 atm
Now we have to calculate the solubility.
As, the solubility of argon in 1 atm pressure = 
So, the solubility of argon in 0.0093 atm pressure = 
= 
Thus, the solubility is, 
Weigh them both and there you go
Answer:

Explanation:
Hello there!
In this case, since the mass percentages in a compound which is wanted to know the molecular formula, can be assumed to be the masses, we first need to compute the moles they have in the formula unit:

Next, we divide each moles by the fewest ones (3.73 mol) in order to find the subscript in the empirical formula first:

Then, the empirical formula is BH2N whose molar mass is 26.83 g/mol, so the ratio of molecular to empirical is 80.50/26.83=3; therefore, the molecular formula is three times the empirical one:

Best regards!
