Why does hydrogen fluoride have a high boiling point
mezya [45]

The intermolecular bonding for HF is van der Waals, whereas for HCL, the intermolecular bonding is hydrogen. Since the van der Waals bond is stronger than hydrogen, HF will have a higher boiling temperature. Since the covalent bond is stronger than van der Waals, HF will have a higher boiling temperature.

What is the mass in grams of 394 mL of ethylene glycol? Express your answer with the appropriate units.
AleksandrR [38]

Answer : The mass of ethylene glycol is, 437.34 grams

Solution : Given,

Volume of ethylene glycol = 394 ml

Density of ethylene glycol = 1.11 g/ml    (Standard value)

Formula used :

Density=\frac{Mass}{Volume}

Now put all the given values in this formula, we get the mass of ethylene glycol.

1.11g/ml=\frac{Mass}{394ml}

Mass=437.34g

Therefore, the mass of ethylene glycol is, 437.34 grams
