Answer 2

Ответ:

Объяснение:

Дано

n(H2SO4) = 4 моль

М(H2SO4) = 98 г/моль

Найти

m(H2SO4)

m(H2SO4) = n * M = 4 моль * 98 г/моль = 392 г

Answer 3

To determine the mass of 4 moles of H2SO4 (sulfuric acid), we need to know its molar mass. Let's calculate it step by step:

1. Find the molar mass of hydrogen (H): The molar mass of hydrogen (H) is approximately 1.008 g/mol.

2. Find the molar mass of sulfur (S): The molar mass of sulfur (S) is approximately 32.06 g/mol.

3. Find the molar mass of oxygen (O): The molar mass of oxygen (O) is approximately 16.00 g/mol.

4. Find the molar mass of sulfuric acid (H2SO4): H2SO4 contains 2 hydrogen atoms, 1 sulfur atom, and 4 oxygen atoms.

Molar mass of H2SO4 = (2 * molar mass of H) + (1 * molar mass of S) + (4 * molar mass of O) Molar mass of H2SO4 = (2 * 1.008 g/mol) + (1 * 32.06 g/mol) + (4 * 16.00 g/mol) Molar mass of H2SO4 = 2.016 g/mol + 32.06 g/mol + 64.00 g/mol Molar mass of H2SO4 = 98.076 g/mol

5. Calculate the mass of 4 moles of H2SO4: Mass = Number of moles * Molar mass Mass = 4 moles * 98.076 g/mol Mass = 392.304 g

The mass of 4 moles of H2SO4 is approximately 392.304 grams.
