Question

Визнач масу 9,5 моль ZnSO3

Answer 1

Ответ:

возможно не правильно.

Дано:                                        

n(ZnSO₃) - 9.5 моль                m(ZnSO₃) = n(ZnSO₃) × M(ZnSO₃)

M(ZnSO₃) - 113 г моль              m(ZnSO₃) = 9.5 × 113 = 1,073.5

m(ZnSO₃) ₋ ?

Answer 2

To determine the mass of 9.5 moles of ZnSO3 (zinc sulfite), we need to know the molar mass of ZnSO3.

The molar mass of an element or compound is the mass of one mole of that substance and is expressed in grams per mole (g/mol).

To find the molar mass of ZnSO3, we add up the individual atomic masses of its constituent elements:

Zn (Zinc) atomic mass: 65.38 g/mol S (Sulfur) atomic mass: 32.06 g/mol O (Oxygen) atomic mass: 16.00 g/mol

Molar mass of ZnSO3 = (1 × Zn) + (1 × S) + (3 × O) Molar mass of ZnSO3 = (1 × 65.38) + (1 × 32.06) + (3 × 16.00) Molar mass of ZnSO3 = 65.38 + 32.06 + 48.00 Molar mass of ZnSO3 = 145.44 g/mol

Now that we have the molar mass of ZnSO3, we can find the mass of 9.5 moles:

Mass of 9.5 moles of ZnSO3 = 9.5 moles × 145.44 g/mol Mass of 9.5 moles of ZnSO3 = 1381.88 grams

Therefore, the mass of 9.5 moles of ZnSO3 is approximately 1381.88 grams.
