Calculate the molecular mass of na2o,nh3. (given atomic mass of na=23)

1.	Calculate the molecular mass of na2o,nh3. (given atomic mass of na=23) *
Answer» ong>EXPLANATION: MOLECULAR MASS of Na2O = 2 × ATOMIC mass of Na (sodium) + 1 × atomic mass of O (Oxygen) = 2 × 23 + 1 × 16 = 46 + 16 = 62u Molecular mass of NH3 = 1 × atomic mass of N (Nitrogen)+ 3 × atomic mass of H (Hydrogen) = 1 × 14 + 3 × 1 = 14 + 3 = 17u Hope this helps you!!

Calculate the molecular mass of na2o,nh3. (given atomic mass of na=23) *

Answer»

= 2 × ATOMIC mass of Na (sodium) + 1 × atomic mass of O (Oxygen)

= 2 × 23 + 1 × 16

= 46 + 16

= 62u

Molecular mass of NH3

= 1 × atomic mass of N (Nitrogen)+ 3 × atomic mass of H (Hydrogen)

= 1 × 14 + 3 × 1

= 14 + 3

= 17u

Hope this helps you!!
