In ferromagnetic materials, smaller groups of atoms band together into areas called domains, in which all the electrons have the same magnetic orientation. That's why you can magnetize them. See how it works in this tutorial.

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

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