Question

Определить массу кварца образованного при разложении 40 килограммов силиката кальция кальция. если выход продукта равен 97%

Answer 1

Молярная масса силиката кальция 116 г/моль. Количество 40 кг /0,116 кг/моль=344,8 моль. Молярная масса SiO2 = 60. Теоретический выход 62*344,8/1000=21,38 кг. Реальный выход 21,28*97/100=20,7кг

Answer 2

Calculation of Quartz Mass

To determine the mass of quartz formed during the decomposition of 40 kilograms of calcium silicate, we need to consider the yield of the product. In this case, the yield is given as 97%.

The mass of quartz formed can be calculated using the following formula:

Mass of quartz = Mass of calcium silicate × Yield of quartz

Substituting the given values:

Mass of quartz = 40 kilograms × 97%

Calculating the result:

Mass of quartz = 40 kilograms × 0.97 = 38.8 kilograms

Therefore, the mass of quartz formed during the decomposition of 40 kilograms of calcium silicate, with a yield of 97%, is approximately 38.8 kilograms.

Please note that the above calculation assumes that the yield of quartz is based on the mass of calcium silicate. If the yield is based on another factor, please provide additional information for a more accurate calculation.
