Question

write the molar masses of Nitrogen dioxide Sulphur Dioxide carbon dioxide compounds​

Answer 1

Answer:

molar mass = molecular mass there Nitrogen =14 mol and oxygen =12 nitrogen dioxide = NO2

MOLAR MASS = 14+12×2=38

sulphur dioxide = SO2

carbon dioxide=Co2

Answer 2

Molar masses

Nitrogen - 14g

Oxygen - 16g

Sulphur - 32g

Carbon -12g

Compounds:-

(i)Nitrogen dioxide (NO2) - 14 + 2(16)

= 14+32 = 46g

(ii) Sulphur Dioxide( SO2) - 32 + 2(16)

= 32 + 32= 64g

(iii) Carbon Dioxide (CO2) - 12 + 2(16)

= 12 + 32 = 44g
