According to the equation, for each gram formula weight of glass produced, 2 moles of C0 2 gas escape = 2 x 22. 4 = 44. 8 liters. Since 1000 liters = 1 cubic meter, for each kilogram formula weight of glass there will be 44. 8 cu. M. Of C0 2 measured under stand- ard conditions. Then 479. 9 : 44. 8 : : 1000 : x, and x = 93. 34 cubic meters C0 2 under standard conditions. 62 CALCIUM CHAPTER XVIII CALCIUM Pages 192-206 METALLIC calcium is deserving of wider use in the laboratory now that it is co...mparatively cheap. It is far safer for pupils to use than sodium or potassium, and being active enough to decompose water in the cold, it serves admirably to illustrate the properties of a very active metal. The use of calcium chloride as a drying agent and the general topic of deliquescence will naturally be enlarged upon in class in connection with the study of the calcium compounds. The use of concentrated sulphuric acid and of phosphorus pen- toxide as still more efficient drying agents for gases, may be men- tioned here.
