Question

2. Обчисліть масові частки елементів у складній речовині S03​

Answer 1

Ответ:

Объяснение:

Mr (SO3) = 1∙32 + 3∙16 = 32 + 48 =80

ω(S) = 32/80 = 0.4 = 40%

ω(O) = 16*3/80 = 0.6 = 60%

Answer 2

Calculating the Molar Mass of Sulfur Trioxide (SO3)

To calculate the molar mass of sulfur trioxide (SO3), we need to consider the atomic masses of the elements involved and their respective quantities in the compound.

Sulfur (S) has an atomic mass of 32.06 g/mol, and oxygen (O) has an atomic mass of 16.00 g/mol.

The molecular formula for sulfur trioxide (SO3) indicates that there is one sulfur atom and three oxygen atoms in each molecule.

Calculation:

The molar mass of sulfur trioxide (SO3) can be calculated as follows:

Molar mass of SO3 = (Atomic mass of Sulfur) + (3 * Atomic mass of Oxygen)

Molar mass of SO3 = (32.06 g/mol) + (3 * 16.00 g/mol)

Molar mass of SO3 = 32.06 g/mol + 48.00 g/mol

Molar mass of SO3 = 80.06 g/mol

Therefore, the molar mass of sulfur trioxide (SO3) is 80.06 g/mol.
