Question

Какое количество вещества соответствует 490 г серной кислоты H*2SO*4

Answer 1

Молярная масса серной кислоты 98 г/моль 490/98 = 5 моль
Ответ: 5 моль

Answer 2

Amount of Substance in 490g of Sulfuric Acid (H2SO4)

Sulfuric acid has a molar mass of 98.079 g/mol. To find the amount of substance in 490g of sulfuric acid (H2SO4), we can use the formula:

Amount of substance (in moles) = Mass / Molar mass

Substituting the given mass of sulfuric acid: Amount of substance (in moles) = 490g / 98.079 g/mol

Calculating the amount of substance: Amount of substance (in moles) ≈ 4.99 moles

Therefore, 490g of sulfuric acid (H2SO4) corresponds to approximately 4.99 moles of the substance.
