Question

Вычислите относительную молекулярную массу серной кислоты

Answer 1

$M_r(H_2SO_4)=2A_r(H)+A_r(S)+4A_r(O)$=2·1+32+4·16=98

Answer 2

Mr(H₂SO₄) = 1*2 + 32 + 16*4 = 98

Answer 3

Calculation of the Relative Molecular Mass of Sulfuric Acid

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

According to the information provided in the search results, the atomic masses are as follows: - Hydrogen (H): 1 - Sulfur (S): 32 - Oxygen (O): 16

The molecular formula of sulfuric acid is H2SO4, which means it contains 2 hydrogen atoms, 1 sulfur atom, and 4 oxygen atoms.

To calculate the relative molecular mass, we sum up the atomic masses of all the atoms in the compound:

Relative Molecular Mass of Sulfuric Acid (H2SO4) = (2 * Atomic Mass of Hydrogen) + Atomic Mass of Sulfur + (4 * Atomic Mass of Oxygen)

Substituting the atomic masses: Relative Molecular Mass of Sulfuric Acid (H2SO4) = (2 * 1) + 32 + (4 * 16)

Calculating the values: Relative Molecular Mass of Sulfuric Acid (H2SO4) = 2 + 32 + 64 = 98

Therefore, the relative molecular mass of sulfuric acid (H2SO4) is 98
