P(total)=P1+P2+P3+...
P(total)=P(N2)+P(others)+P(O2)
100kPa=78kPa+1kPa+P(O2)
P(O2)=100-79=21kPa
Oil-based food coloring used to make the letters, won't dissolve in water. According to some sources, oil-based food coloring is either insoluble or immiscible in water. Because it is present in more solutions, water serves as the universal solvent.
<h3>
Universal solvent:-</h3>
A substance that displaces most compounds is known as a universal solvent. Because it dissolves more chemicals than any other solvent, water is known as the universal solvent.
<h3>
What chemicals lack solvability?</h3>
Sand, plastic, wood, metal, glass, and cloth are examples of insoluble materials. At standard conditions of pressure and temperature, these compounds never dissolve in water or any other solvent. Other examples of insoluble materials are sugars and inorganic salts.
