How many moles in a 2.00M & 7.9L solution

15.8 moles

Explanation:

Molarity = moles solute / Volume of Solution in Liters

=> moles of solute = Molarity of Solution X Volume of Solution in Liters

= (2.00M)(7.9L) (2.00moles/L)(7.9L) = 15.8 moles

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.
