What reading level is An Elementary Experimental Chemistry book?
To quickly assess the difficulty of the text, read a short excerpt:
If 150 liters of marsh gas be exploded with 300 liters of oxygen, what volume of carbon dioxid would result ?
Calculation of Percentage Composition, having given the Molecular Formula. It is often required that the student should be able to calculate the percentage composition of a compound when the molecular formula is known. Suppose we have given the formula for alcohol, which is C 2 H 6 O.
Carbon ax 12 = 24 Hydrogen 6 x i = 6 Oxygen i x 16 = 16 Molecular weight = 46 In alcohol, therefore, th...ere are 12 parts by weight of carbon, 6 parts of hydrogen, and 16 of oxygen. This reduced to the decimal system becomes Carbon ^ = 52-17% Hydrogen = 13-05 % Oxygen = 34. 78 % 100. 00 % In case there is water of crystallization in the compound, the water molecules combined with each molecule of the compound must also be taken into account.
Examples, i. Calculate the percentage composition of AgCl; NaN0 3 ; Ca 3 (PO 4 ) 2 ; CHC1 3 ; K 4 Fe(CN) 6 ; (NH 4 ) 2 SO 4 .
2. Calculate the percentage composition of MgSO 4, 7H 2 O; HNaNH 4 P0 4, 4 H 2 O.
