What is the molecular formula for a compound, having a empirical formula of ch20 and a molar mass of 150 g/mol

The molecular formula is C₅H₁₀O₅.

EF = CH₂O

EF Mass = (12.01 + 2.016 + 16.00) u = 30.03 u

MF mass = 150 u

MF = (EF)_n

n = MF Mass/EF Mass = 150 u/30.03 u = 4.995 ≈ 5

MF = (CH₂O)₅ = C₅H₁₀O₅

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
