Question

Молекулярная масса MeXO4 равна 183 г/моль. Разница молекулярных масс X2O3 и MeSO3 равна 14 а.е.м. Определите молекулярную массу XSO4​

Answer 1

Ответ:

Пусть M - молярная масса Me, X - молярная масса X, тогда по условию:

M+X+64 = 183, M+X = 119 г (1);

2*X+48-(M+80) = 14 (2), выражаем M из (1), и подставляя в (2), получаем 2*X+48-(119-X+80) = 14, откуда X = 55 г/моль;

т.о. M XSO4 = 55+96 = 151 г/моль.

Answer 2

Molecular Mass Calculations

To determine the molecular mass of XSO4, we can use the given information about the molecular mass of MeXO4 and the difference in molecular masses between X2O3 and MeSO3.

The molecular mass of MeXO4 is given as 183 g/mol, and the difference in molecular masses between X2O3 and MeSO3 is 14 atomic mass units (a.m.u).

First, let's calculate the molecular mass of X2O3 and MeSO3 using the given information.

The molecular mass of X2O3 can be represented as 2X + 3O, and the molecular mass of MeSO3 can be represented as Me + S + 3O.

Calculation Steps

1. Molecular Mass of X2O3: - The molecular mass of X2O3 can be calculated as 2X + 3O. - Given that the difference in molecular masses between X2O3 and MeSO3 is 14 a.m.u, we can represent the molecular mass of X2O3 as (MeSO3 - 14).

2. Molecular Mass of MeSO3: - The molecular mass of MeSO3 can be represented as Me + S + 3O. - Given that the molecular mass of MeXO4 is 183 g/mol, we can represent the molecular mass of MeSO3 as (MeXO4 - X + O).

Now, let's use these representations to calculate the molecular mass of X2O3 and MeSO3.

Calculation of Molecular Masses

1. Molecular Mass of X2O3: - Molecular mass of X2O3 = (MeSO3 - 14)

2. Molecular Mass of MeSO3: - Molecular mass of MeSO3 = (MeXO4 - X + O)

Final Step: Calculating Molecular Mass of XSO4

Now that we have the representations for the molecular masses of X2O3 and MeSO3, we can use these to calculate the molecular mass of XSO4.

The molecular mass of XSO4 can be represented as X + S + O + 4O.

Using the calculated molecular masses of X2O3 and MeSO3, we can determine the molecular mass of XSO4.

I hope this helps! Let's continue the calculation to find the molecular mass of XSO4.
