Mass of the steel is
- density of a substance can be regarded as the ratio of the mass of that substance to that of it's volume.
- Mass of substance can be regarded as the quantitative measure of inertia, it can be simply explained as a fundamental property of all matter
<em> We can express this mathematically as ;</em>
Given :
Density of this steel= 8.1g/cm3
If we make Mass subject of formula,
Then let us substitute the values into the expression
Therefore, mass of the steel is

Answer: polar molecule.
Explanation:
The boiling point is the temperature at which the vapor pressure of a liquid equals the external pressure surrounding the liquid. The boiling point is dependent on the type of forces present.
Iodine monochloride (ICl) is a polar molecule due to the difference in electronegativities of iodine and chlorine. Thus the molecules are bonded by strong dipole dipole forces. Thus a higher temperature is needed to generate enough vapor pressure.
Bromine is a non polar molecule as there is no electronegativity difference between two bromine atoms. The molecules are bonded by weak vanderwaal forces and thus has low boiling point.
