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
vlada-n [284]

Answer: 2.4 ml

Solution :

Molar mass of NH_3 = 17 g/mole

Given,: 28% w/w of NH_3 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.

Volume=\frac{Mass}{Density}=\frac{100g}{0.899g/ml}=111.2ml  

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

Molarity=\frac{n\times 1000}{V_s}

where,

n = moles of solute NH_3=\frac{\text {given mass}}{\text {molar mass}}=\frac{28}{17}=1.65moles

V_s = volume of solution in liter = 0.11 L

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

Molarity=\frac{1.65moles}{0.11L}=15mole/L

Using molarity equation:

M_1V_1=M_2V_2

15\times V_1=0.036\times 1.0\times 10^{3}

V_1=2.4ml

Please help meeeeee brainly given!
Alla [95]
If gravity is the ONLY force acting on an object, then the force of
Earth's gravity produces acceleration of 9.8 meters per second²
downward.  That number doesn't change, and it doesn't depend
on the mass or weight of the object.

If there are any other forces acting on the object at the same time,
like air resistance or some other kind of friction for example, then
all bets are off, and we can't say what the object's acceleration will
be in that case.

Why is an amide less reactive to nucleophilic acyl substitution than an acid chloride?
Olin [163]

An amide is less reactive to nucleophilic acyl substitution than an acid chloride because more electron density is donated to the carbonyl by nitrogen.

<h3>What is electron density?</h3>

In quantum chemistry, electron density, also known as electronic density, is a metric for the likelihood that an electron will be found at a microscopic portion of space surrounding a specific point. The likelihood of finding an electron at a particular position near an atom or molecule is represented by electron density. In general, areas with a high electron density are where the electron is most likely to be located. The attractive forces between the electrons and the nuclei in a molecule are what hold the nuclei together in molecule, hence the electron density is essential to the bonding and geometry of a molecule. The repulsions between the nuclei and the electrons function as an antagonist to these attractive forces.
