Question

Порівняйте, що більше - маса трьох молекул кисню О2 чи однієї молекули сульфатної кислоти Н2SО4​

Answer 1

Ответ:

Маса H2SO4 > маса 3 молекул О2

Объяснение:

Маса 3 молекул О2 = (16×2)×3 = 32×3 = 96

Маса молекули H2SO4 = 1×2 + 32 + 16×4 = 2+32+64 = 98

Answer 2

Comparison of the Mass of Three Oxygen Molecules (O2) and One Sulfuric Acid Molecule (H2SO4)

When comparing the mass of three oxygen molecules (O2) and one molecule of sulfuric acid (H2SO4), it's important to consider the molecular weights of each substance.

Molecular Weights: - The molecular weight of oxygen (O2) is approximately 32 g/mol. - The molecular weight of sulfuric acid (H2SO4) is approximately 98 g/mol.

Calculation: - The total mass of three oxygen molecules (O2) can be calculated as 3 * 32 g/mol = 96 g/mol. - The mass of one molecule of sulfuric acid (H2SO4) is 98 g/mol.

Comparison: - Therefore, the mass of three oxygen molecules (O2) is 96 g/mol, while the mass of one molecule of sulfuric acid (H2SO4) is 98 g/mol.

This comparison shows that the mass of one molecule of sulfuric acid (H2SO4) is slightly greater than the combined mass of three oxygen molecules (O2).
