Answer 1

Ответ:

Объяснение:

Mr (MgCO3) = 24 + 12 + 16*3 = 84

24 : 12 : 48 | : 12 (делим на наименьшее)

2 : 1 : 4

Answer 2

Mass Ratios of Elements in MgCO3

To calculate the mass ratios of elements in MgCO3, we can use the molar masses of each element to determine the proportion of each element in the compound.

The molar mass of MgCO3 can be calculated as follows: - Molar mass of Mg = 24.305 g/mol - Molar mass of C = 12.011 g/mol - Molar mass of O = 15.999 g/mol

Using these molar masses, we can calculate the mass ratios of each element in MgCO3.

Molar Mass Calculation: - Mg: 24.305 g/mol - C: 12.011 g/mol - O: 15.999 g/mol

Mass Ratios: - Mg: 24.305 g/mol - C: 12.011 g/mol - O: 15.999 g/mol

Therefore, the mass ratios of Mg, C, and O in MgCO3 are approximately: - Mg: 24.305 g/mol - C: 12.011 g/mol - O: 15.999 g/mol
