How many moles are jn 1.25x 1025 molecules of C3H6O?

For getting the  number of moles we can divide 1.2 x 1024/6.02 x 1023 and we receive 2 moles.

h let me think

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.
