This is covalent network type of solid.
For example, silicon dioxide (SiO₂) is covalent network solid with covalent bonding.
Covalent network solid is a chemical compound (or element) in which the atoms are bonded by covalent bonds in a continuous network extending throughout the material.
Silicon(IV) oxide has continuous three-dimensional network of SiO₂ units and diamond has sp3 hybridization.
This solids do not have free electrons so they are good insulators.
They have strong covalent bonds, so they melt at extremely high temperature.
Other examples are quartz, diamond, and silicon carbide.

d) T3 and T4. T3 and T4 are poorly soluble in water, and more than 99% of the T3 and T4 circulating in blood is bound to carrier proteins. The main carrier of thyroid hormones is thyroxine-binding globulin, a glycoprotein synthesized in the liver.
Mass= number of moles multiply Mass of one mole
= 24.3 multiplied by 4
= 96.2
Because you are never 100% precise during the work, so it's best and most accurate answer is always the average of more trials. basically the more you do, the more accurate the answer shall be
