Question

Рассчитайте относительную молекулярную массу серной кислоты h2 so4. НАПИШИТЕ ПОДРОБНО!!!

Answer 1

Атомная масса водорода = 1
серы = 32
кислорода = 16

Н2SO4
теперь складываем все атомные массы
1*2 + 32 + 16*4 = 98 грамм/моль
это и есть ответ

Answer 2

Равна сумме относительных атомных масс, входящих в её состав элементов, умноженных на число атомов этих элементов.

Answer 3

Calculation of the Relative Molecular Mass of Sulfuric Acid (H2SO4)

To calculate the relative molecular mass of sulfuric acid (H2SO4), we need to consider the atomic masses of the elements present in the compound and their respective stoichiometric coefficients.

The molecular formula of sulfuric acid is H2SO4. Let's break down the calculation step by step:

1. Determine the atomic masses of the elements: - Hydrogen (H): Atomic mass = 1.00784 - Sulfur (S): Atomic mass = 32.06 - Oxygen (O): Atomic mass = 15.999

2. Multiply the atomic masses by the stoichiometric coefficients: - Hydrogen (H): 2 atoms * 1.00784 g/mol = 2.01568 g/mol - Sulfur (S): 1 atom * 32.06 g/mol = 32.06 g/mol - Oxygen (O): 4 atoms * 15.999 g/mol = 63.996 g/mol

3. Sum up the individual masses: - Hydrogen (H): 2.01568 g/mol - Sulfur (S): 32.06 g/mol - Oxygen (O): 63.996 g/mol

4. Calculate the relative molecular mass (also known as the molar mass or molecular weight) by adding up the individual masses: - Relative molecular mass of H2SO4 = 2.01568 g/mol + 32.06 g/mol + 63.996 g/mol = 98.08168 g/mol

Therefore, the relative molecular mass of sulfuric acid (H2SO4) is approximately 98.08 g/mol.

Please note that the atomic masses used in this calculation are approximate and may vary slightly depending on the source.
