Question

Дано: m(SO2)=98г. найти: n= (S02)-?

Answer 1

Ответ:

1,53125

Объяснение:

Так как по формуле n=m/M  ;

M=32(у серы)+ 16*2(у кислорода)=64  =>

n=96/64=1,53125

Answer 2

To find the amount of substance (n) of SO2 (sulfur dioxide), we need to use its molar mass and the given mass (m) of SO2.

1. Find the molar mass of SO2: The molar mass of sulfur (S) is approximately 32.06 g/mol, and the molar mass of oxygen (O) is approximately 16.00 g/mol. To calculate the molar mass of SO2, we add the molar masses of sulfur and two oxygen atoms.

Molar mass of SO2 = (1 * molar mass of S) + (2 * molar mass of O) Molar mass of SO2 = (1 * 32.06 g/mol) + (2 * 16.00 g/mol) = 64.06 g/mol

2. Calculate the amount of substance (n) of SO2 using the given mass (m) and molar mass:

n = m / Molar mass n = 98 g / 64.06 g/mol ≈ 1.529 mol

So, the amount of substance of SO2 is approximately 1.529 moles.
