At 1 atm and 273 K the volume of nitrogen gas required to cover a sample of silica gel, assuming Langinuin monolayer adsorption, is found to be 1.30 cm^3 g^(-1) of the gel. The area occupied by a nitrogen molecule is 0.16 nm^(2) . What is the surface area per gram of silica gel? [Given : N_A = 6 xx 10^(23)]

How does amorphous silica differ from quartz?

Carborundum is obtained when silica is strongly heated with
