Question

M(NO2)=198g V(NO2)=?

Answer 1

V=Vm*n
n=m:M
M(NO2)=32+14=46g/моль
n(NO2)=198g:46g/моль=4.304 моль
V(NO2)=22,4 дм3/моль*4.304 моль=96.417 дм3
Ответ:96.417 дм3.

Answer 2

To find the volume of a substance, such as nitrogen dioxide (NO2), you would need more information than just the mass (M) of the substance. You would also need to know the substance's density or molar mass and the conditions under which you want to calculate the volume (e.g., temperature and pressure).

The formula to calculate the volume of a substance (V) is:

V = (Molar mass of the substance) * (Mass of the substance) / (Density of the substance)

If you have the molar mass of nitrogen dioxide (NO2), the density of NO2, and the mass (198 grams), you can use this formula to calculate the volume. However, if you don't have the density or molar mass, you won't be able to find the volume. The molar mass of NO2 is approximately 46 grams/mol, but you would still need the density to calculate the volume accurately.

If you can provide the density and temperature/pressure conditions, I can help you calculate the volume of NO2.
