I think the answer is B. But I am not sure
Answer:
<span>The strongest intermolecular interactions between hydrogen fluoride (hf) molecules arise from Hydrogen Bonding.
Explanation:
Hydrogen Bond interactions are considered the strongest intermolecular interactions among molecules. These interactions are found between Hydrogen atom of one molecule bonded to most electronegative atoms (i.e F, O, N) and the most electronegative atoms of neighbor molecule.
In case of HF, fluorine has the greatest electronegativity of 4, so the hydrogen bonded to Fluorine becomes partial positive and makes Hydrogen bond with Fluorine atom of </span>neighbor HF molecule.<span />

if it has to be 2 of these I think it would be A and B but if it is only one Answer it would be B
Answer:
Mass = 0.158 g
Explanation:
Formula used,
P V = n R T
Or,
n = P V / R T
Putting values,
n = 0.948 atm . 0.025 L / 0.0821 L.atm.K⁻¹.mol⁻¹ . 291.45
n = 0.00099 mol
Note: we have changed pressure from mmHg to atm, volume from mL to L and temperature from C to K)
Also,
Mass = n . Molecular Mass
Mass = 0.00099 mol × 159.808 g/mol
Mass = 0.158 g
