Answer:
Explanation:
Convert molecules to moles:
1 mole of NaNO₃= 6.02 x 10^23 molecules of NaNO₃
7.3 x10^24/(6.02 x 10^23)=12mol NaNO₃
Find molar mass:
NaNO₃=1 mole of Na and 1mole of N and 3mole of O
Find grams:
14.01g x 12= 168.12 g of N
Answer:

Explanation:
Hello,
In this case, considering that the density is defined as:

Thus, since 1 kg equals 1000 g and 1 L equal 1000 mL, the required density in g/mL turns out:

Take into account that since 0.65 L has two significant figures, the result is also shown with two significant figures.
Regards.
Answer:
single replacement reaction.
Answer:
See explanation below
Explanation:
First, we need to understand that the monochlorination of an alkane like this one, involves substitution of one of the atoms of hydrogen of the molecule for an atom of chlorine.
This reaction takes place when the alkane reacts with Cl₂ in presence of light or heat.
When this happens, the first step involves the breaking of the double bond of the chlorine to form the ion Cl⁻.
The next step involves the substraction of the hydrogen of the molecule by the Chlorine. This will leave the alkane with a lone pair available for reaction.
The third step, the alkane with the lone pair of electron substract a chlorine for the beggining and form the mono chlorinated product.
The final step involves forming the remaining products with the remaining reagents there.
In the picture attached you have the mechanism and product for this reaction:
