Question

Какова молярная масса бензола (г/моль). Ответ подтвердите расчетами.

Answer 1

C6H6
Mr=12×6+6×1=76гр/ моль

Answer 2

Формула бензола = C6H6
молярная масса бензола = 78 г/моль
M(C6H6)=12*6 + 1*6 = 78

Answer 3

Molar Mass of Benzene (C₆H₆)

The molar mass of benzene (C₆H₆) can be calculated by summing up the atomic masses of its constituent atoms. Benzene consists of 6 carbon atoms (C) and 6 hydrogen atoms (H).

The atomic mass of carbon (C) is approximately 12.01 g/mol, and the atomic mass of hydrogen (H) is approximately 1.01 g/mol.

To calculate the molar mass of benzene, we can use the following formula:

Molar mass of benzene = (6 * atomic mass of carbon) + (6 * atomic mass of hydrogen)

Substituting the atomic masses, we get:

Molar mass of benzene = (6 * 12.01 g/mol) + (6 * 1.01 g/mol)

Calculating this expression gives us:

Molar mass of benzene = 72.06 g/mol + 6.06 g/mol

Therefore, the molar mass of benzene is approximately 78.12 g/mol.
