What volume, in Liters, of a 2.00 M KCl solution contains 2.5kg of KCl? Molar mass of KCl= 74.55g/mole

Julli [10]

$C_{m}=\frac{n}{V_{r}}\\\\
n=\frac{m_{s}}{M}\\\\
C_{m}=\frac{m_{s}}{MV_{r}} \ \ \ |*MV_{r}\\\\
C_{m}MV_{r}=m_{s} \ \ \ |:C_{m}M\\\\
V_{r}=\frac{m_{s}}{C_{m}M}\\\\\\
m=2.5kg=2500g\\
M=74.55\frac{g}{mol}\\
C_{m}=2\frac{mol}{L}\\\\
V_{r}=\frac{2500g}{2\frac{mol}{L}*74.55\frac{g}{mol}}\approx16.77L$

What kind of intermolecular forces act between two ammonia molecules

iragen [17]

Answer:

extensive hydrogen bonding

Explanation:

The high boiling points of water, hydrogen fluoride (HF) and ammonia (NH3) is an effect of the extensive hydrogen bonding between the molecules. The London dispersion force is caused by random and temporary changes in the polarity of atoms, caused by the location of the electrons in the atoms' orbitals.

Hope this helps :)
