What volume of water should be added to 4.6 g of KCl to make 4m solution

Chemistry
1 answer:
dusya [7]3 years ago

Answer:

Explanation:

We want 4M, or 4 moles/liter.  4.6g of KCl is (4.0g KCl/74.55g/mole KCl) = 0.0617 moles of KCl.

Write the definition of Molar and set the volume to X ( X will tell us how many liters are needed to make a 4M solution from 0.0617 moles of KCl)

4.0M = (0.0617 moles KCl)/X

(4.0 moles/liter)*X = 0.0617 moles KCl

X = (0.0617 moles KCl)/(4.0 moles KCl)

X = 0.0154 liters, or 15.4 ml

===

[(0.0154 liters)*(4.0 moles/liter) = 0.0617 moles KCl]

Answer: Option (c) is the correct answer.

Explanation:

In liquids, molecules are held by slightly less strong intermolecular forces of attraction as compared to solids.

Hence, molecules of a liquid are able to slide past each other as they have more kinetic energy than the molecules of a solid.

As a result, liquids are able to occupy the shape of container in which they are placed. Also, liquids have fixed volume but no fixed shape.

Thus, we can conclude that liquids have a variable shape and a fixed volume.
