Question

Определите в каком из соединений больше содержится калия: сульфате калия, хлориде калия или калийной селитре? Свой ответ подтвердите расчетами.

Answer 1

В сульфате калия, потому что K2SO4=2K+SO4

Answer 2

Ответ:

K2SO4=2K+SO4

Answer 3

Determining the Content of Potassium in Different Compounds

To determine in which compound there is more potassium content among potassium sulfate, potassium chloride, and potassium nitrate, we can calculate the molar masses of each compound and then compare the amount of potassium in each.

Molar Mass Calculation

The molar masses of the compounds are as follows: - Potassium sulfate (K2SO4): 174.26 g/mol - Potassium chloride (KCl): 74.55 g/mol - Potassium nitrate (KNO3): 101.1 g/mol

Calculating Potassium Content

1. Potassium Sulfate (K2SO4) - Molar mass: 174.26 g/mol - Potassium content: 2 * 39.10 g/mol = 78.20 g/mol

2. Potassium Chloride (KCl) - Molar mass: 74.55 g/mol - Potassium content: 39.10 g/mol

3. Potassium Nitrate (KNO3) - Molar mass: 101.1 g/mol - Potassium content: 39.10 g/mol

Comparison of Potassium Content

Based on the calculations, the potassium content in each compound is as follows: - Potassium sulfate (K2SO4): 78.20 g/mol - Potassium chloride (KCl): 39.10 g/mol - Potassium nitrate (KNO3): 39.10 g/mol

Therefore, potassium sulfate (K2SO4) contains more potassium compared to potassium chloride (KCl) and potassium nitrate (KNO3).

This conclusion is supported by the molar masses and the amount of potassium in each compound.
