Question

a solid sol is made up of two solid a and b mass percentage a is 60% by mass in a solid sol
find the molar mass of b if mole fraction of a is 0.20 and molar mass of a is 100g/mol

Answer 1

Here is your answer

A solid is a sample of matter that retains its shape and density when not confined. ... Examples of solids are common table salt, table sugar, water ice, frozen carbon dioxide (dry ice), glass, rock, most metals, and wood. When a solid is heated, the atoms or molecules gain kinetic energy .
