Question

Problema:In ce cantitate de metan se gaseste aceeasi cantitate de hidrogen ca in 10 moli amoniac.

Answer 1

NH3  miu(M)=(14gN+3x1gH)/mol= 17g/mol
 1mol NH3...are  ...   3gH
10mol....................m=30gH

CH4  miu(M)= (12gC+4x1gH)/mol=16g/mol
16g CH4   ,,contine,,,,4gH
m...................................30g
m= 16x30/4=...........................calculeaza !!!!
