A 10.0cm3 volume of alcohol has a mass of 7.05g. What the density

VMariaS [17]

A 10.0cm3 volume of alcohol has a mass of 7.05g. $0.705 \frac{g}{c m^{3}}$ is the density

Answer: $0.705 \frac{g}{c m^{3}}$

<u>Explanation:</u>

The ratio between the mass of a substance and its unit volume is referred as density.

$\text {Density}=\frac{\text { mass }}{\text { volume }}=\frac{7.05 g}{10.0 \mathrm{cm}^{3}}=0.705 \frac{g}{\mathrm{cm}^{3}}$ is the Answer

<u>Note:</u>

1000 g = 1 kg

100 cm = 1 m

When we used to transform the given values into S.I units, then

$\text {Density}\left(\frac{k g}{m^{3}}\right)=\frac{\text {Mass}(k g)}{\text {Volume}\left(m^{3}\right)}$

Alcohol’s volume can be written as, $10.0 c m^{3} = 10 \times 10^{-2} m^{3}$

Alcohol’s mass can denote as, $7.05 g = 7.05 \times 10^{-3} \mathrm{kg}$

Then, $\text { Density }\left(\frac{k g}{m^{8}}\right)=\frac{, 00705(k g)}{0.1\left(m^{3}\right)} = .0705 \frac{\mathrm{kg}}{\mathrm{m}^{\mathrm{s}}}$

How many monochlorination products can be formed (constitutional isomers only) from the reaction of (CH3)2CHCH2CH3 with Cl2 and

faltersainse [42]

Answer:

4 monochlorination products can be formed.

Explanation:

Constitutional isomers : These are those compounds with same molecular formula but different atomic arrangement.For example: butane and 2-methly-propane.

On monochlorination of 2 methyl-butane we will have four possibilities of product which will be constitutional isomers of each other:

1-chloro-3-methyl butane : $(CH_3)_2CH-CH_2-CH_2-Cl$

2-chloro-3-methyl butane : $(CH_3)_2CH-CHCl-CH_3$

2-chloro-2-methyl butane $(CH_3)_2CCl-CH_2-CH_3$
1-chloro-2-methyl butane $(CH_2Cl)_2CH-CH_2-CH_3$

Critical thinking : Place an unmagnetized piece of iron in a magnetic field (eg iron filings near a magnet). Why is it attracted

inysia [295]

Magnets attract iron due to the influence of their magnetic field upon the iron. Before a piece of iron enters the magnet, the polarization of the irons atoms is random. When exposed to the magnetic field, the atoms begin to align their electrons with the flow of the magnetic field, which makes the iron magnetized as well. This, in turn, creates an attraction between the two magnetized objects. This is why a piece of iron that is exposed to a magnet becomes magnetic for some time afterward.
