Please help, will give brainliest N2 + 3H2 + 2NH3
Calculate the mass of N, that would be needed to produce from 75.0g of NH3?
Show your work by including all values used to determine the answer.

Mass = 61.6 g

Explanation:

Given data:

Mass of ammonia produced = 75.0 g

Mass of nitrogen needed = ?

Solution:

Chemical equation:

N₂ + 3H₂    →      2NH₃

Number of moles of ammonia:

Number of moles = mass/molar mass

Number of moles = 75 g/ 17 g/mol

Number of moles =  4.4 mol

No we will compare the moles of ammonia with nitrogen.

              NH₃           :          N₂

                2             :           1

               4.4           :          1/2×4.4 =2.2 mol

Mass of N₂:

Mass = number of moles × molar mass

Mass = 2.2 mol × 28 g/mol

Mass = 61.6 g

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
