The density of concentrated ammonia, which is 28.0% w/w nh3, is 0.899 g/ml. what volume of this reagent should be diluted to 1.0 × 103 ml to make a solution that is 0.036 m in nh3

2.4 ml

Solution :

Molar mass of = 17 g/mole

Given,: 28% w/w of solution means 28 g of ammonia in 100 g of solution.

Mass of solution = 100 g

Now we have to calculate the volume of solution.

Molarity : It is defined as the number of moles of solute present in one liter of solution.

where,

n = moles of solute

= volume of solution in liter = 0.11 L

Now put all the given values in the formula of molarity, we get

Using molarity equation:

the answer to your question is c
