How many grams of silica gel per cubic inch?

Answer 1

The density of silica gelat 20°C (68°F)

ranges from2.17 to 2.66 gm per cm³ (cu. cm.). (See source link.)

You want the answer in grams per cubic inch.There are

16.34cubic centimetres per cubic inch (approx.). Therefore, there would be this times the mass of silica gel in a cubic inch of the stuff as in a cubic centimetre of it.

Then the number of grams of silica gel per cubic inch would range from 2.17 x 16.34 to 2.66 x 16.34 or from 35.46 to 43.46.
