Question

N(SO2) = 54 * 10^23 Найти : m-? V-?

Answer 1

N(SO₂) = 54·10²³

Vm=22,4л./моль

Найти :

m-?

V-?

Решение:

1. n(SO₂)=N(SO₂) ÷ Na

n(SO₂)=54·10²³молекул ÷ 6,02молекул/моль=8,97моль

2. M(SO₂)=32+32=64г./моль

3. m(SO₂)=n(SO₂)хM(SO₂)

m(SO₂)=8,97мольх64г./моль=574,08г.

4. V(SO₂)=n(SO₂)xVm

V(SO₂)=8,97моль×22,4л./моль=200,928л.

5. Ответ: 54·10²³ молекул оксида серы(IV) имеют массу 574,08г. и занимают объем 200,928л.

Answer 2

In the given context, "N(SO2)" represents the number of molecules of SO2 (Sulfur Dioxide). It is given as N(SO2) = 54 * 10^23.

To find "m" (the mass of one molecule of SO2) and "V" (volume occupied by N(SO2) molecules), we'll need some additional information. Specifically, we need the molar mass of SO2 and the conditions under which the volume is measured.

1. Finding "m" (mass of one molecule of SO2): The molar mass of SO2 can be found from the periodic table. 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 find the molar mass of SO2, we add the molar masses of sulfur and two oxygen atoms.

Molar mass of SO2 (m) = 1 * M(S) + 2 * M(O) m ≈ 1 * 32.06 g/mol + 2 * 16.00 g/mol m ≈ 32.06 g/mol + 32.00 g/mol m ≈ 64.06 g/mol

So, the mass of one molecule of SO2 (m) is approximately 64.06 g/mol.

2. Finding "V" (volume occupied by N(SO2) molecules): To determine the volume, we need to know the conditions (temperature and pressure) under which the volume is measured. Without this information, we cannot directly calculate the volume.

Please provide the temperature and pressure at which the volume is measured so that I can proceed with the calculation of "V."
