Answer 1

Чистого СаCО₃ можно получить   20*0,82=16,4 кг

Answer 2

Calculating the Amount of Pure CaCO₃ from Limestone

To calculate the amount of pure CaCO₃ that can be obtained from 20 kg of limestone containing 18% impurities, we can use the following steps:

1. Calculate the amount of pure CaCO₃ in the limestone: - The limestone contains 18% impurities, so the remaining 82% is pure CaCO₃. - Calculate the amount of pure CaCO₃ in 20 kg of limestone.

2. Perform the calculation: - Use the result from step 1 to determine the amount of pure CaCO₃ that can be obtained.

Let's proceed with the calculations.
