1) Given 1469 of H₂SO4 how
many moles do you have

15moles

Explanation:

Given parameters:

Mass of H₂SO₄   = 1469g

Unknown:

Number of moles  = ?

Solution:

To solve this problem, let us first find the molar mass of the given compound;

  molar mass = 2(1) + 32 + 4(16)  = 98g/mol

So;

 Number of moles =    =  

 Number of moles  = 15moles

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.

the atomic mass is the bottom number on the element.
