Question

Among the following the best describes the concentration of solution formed by dissolving 4g of NaOH in 1kg of water a) 4gL-1 b) 0.1N c) 0.1M d) 4m

Answer 1

Answer:

11

Explanation:

.

Answer 2

Concept introduction:

The quantity of a material dissolved in a given mass of solvent is known as its molality (m), also known as molal concentration. The moles of a solute per kilogram of a solvent are how it is defined.

Explanation:

Given that, $4$g of NaOH is dissolved in $1$kg of water.

We have to find, which among the given options best describe concentration of the solution.

According to the question,

Here the best way to express concentration of NaOH is in g/l because no other option matches with the formula. And we know that $1$kg of water is same as $1$ liter of water hence the concentration is $4$g/l.  

Final Answer:

Option a) $4$g/l.
