empirical formula = when the percentage compositions by mass of elements in a compound are divided by their relative atomic masses.
from the obtained amount the smallest amount will divide all.
the answers can then be rounded off if in decimals or they can be multiplied by 2 if they have .5 decimals e.g 2.5 , 7.5 , etc.

Explanation:
solution:
These phase changes can be brought about by heating or cooling. ... This kind of phase change--liquid to gas--is called evaporation or vaporization. Water vapor can in turn be cooled to form liquid water. This kind of phase change--from gas to liquid--is referred to as condensation vaporization.
Condensation is the change of the physical state of matter from gas phase into liquid phase, and is the reverse of vaporization. The word most often refers to the water cycle.

Adding carbon to iron to make steel does make it stronger and tougher, up to a point. Then it will get stronger but less tough (ie like cast iron). Carbonstrengthens iron by distorting its crystal latice. This distortion is similar in effect to work hardening.
increases iron’s conductivity.
