Question

what weight of calcium oxide will be formed on heating20.8g of calcium carbonate?​

Answer 1

Hey dude here is your answers............

Where the weights are 100 56 and 44 grams respectively. Thus, 100 gram of calcium carbonate gives 56 gram of calcium oxide so 1 gram will give 56/100 gram of calcium oxide. Hence, 19.3 gram of calcium carbonate will yield 56/100*19.3 = 10.8 gram of calcium oxide......
