NH3 carbon steel construction storage tanks with 0.2 percent by weight or more of water could last more than 50 years in service. Ammonium compounds should never be allowed to come in contact with bases (unless in an intended and contained reaction), as dangerous quantities of ammonia gas could be released. What is the atomic mass of one mole of H? What is the atomic mass of one mole of O? What is the molecular weight of one mole of H2O? How many moles of NH3 are formed? 3Fe + 4H2O Fe3O4 + 4H2 How many molecules of H2 are produced? How many oxygen atoms are found in the products?

Q.:- Calculate the molecular masses of H₂, O₂, Cl₂, CO₂, CH₄, C₂H₆, C₂H₄, NH₃, CH₃OH.

Answer:-

Molecular mass of H₂ = 2 X atomic mass of H = 2 X 1u = 2u

Molecular mass of O₂ = 2 Xatomic mass of O = 2 X 16u = 32u

Molecular mass of Cl₂ = 2 X atomic mass of Cl = 2 X 35.5u = 71u

Molecular mass of CO₂ = atomic mass of C + 2 X atomic mass of O

= 12+ (2+16) = (12 + 32)u = 44u

Molecular mass of CH₄ = atomic mass of C+ 4 X atomic mass of H

= 12+ (4X1)u = (12 + 4)u = 16u

Molecular mass of C₂H₆ = 2 X atomic mass of C + 6 X atomic mass of H

= (2 X 12 + 6 X 1)u = (24 + 6)u = 30u

Molecular mass of C₂H₄ = 2 X atomic mass of C+ 4 X atomic mass of H

= (2 X 12 + 4 X 1)u = (24 + 4)u = 28u

Molecular mass of NH₃ = atomic mass of N + 3 X atomic mass of H

= (14 + 3 X 1)u = (14 + 3)u = 17u

Molecular mass of CH₃OH = atomic mass of C + 3 x atomic mass of H + atomic mass of O

+ atomic mass of H

Atomic Mass Of Nh3

= (12 + 3 X 1 + 16 + 1)u = (12 + 3 + 17)u = 32u
