Assuming 100% dissociation, calculate the freezing point and boiling point (in °C) of a solution with 83.6 g of AgNO 3 in 1.00 k

Thepotemich [5.8K]

Answer:

Freezing point: - 1.83ºC

Boiling point: 100.50ºC

Explanation:

The freezing point and boiling point of solvents, when a solute is added, will change accordingly to the concentration of the solute particles.

The freezing point will decrease and the boiling point will increase. These are two colligative properties.

3. How many moles of NaCl are present in 6000. La 1.5 M NaCl solution?

Leno4ka [110]

Answer:

Option A (9.0) is the correct alternative.

Explanation:

The given values are:

Molarity,

= 1.5 M

Volume,

= 6000 mL

or,

= 6 L

As we know,

⇒ $Molarity=\frac{Moles}{Volume}$

or,

⇒ $The \ moles \ of \ NaCl=Molarity\times Volume$

By putting the values, we get

$=1.5\times 6$

$=9 \ mol$
