Answer:
Mass = 15.13 g
Explanation:
Given data:
Number of atoms of hydrogen = 8.11×10²³
Mass of ammonia formed = ?
Solution:
Chemical equation:
3H₂ + N₂ → 2NH₃
Number of moles of hydrogen:
1 mole contain 6.022× 10²³ atoms
8.11×10²³ atoms × 1 mol / 6.022× 10²³ atoms
1.35 mol
Now we will compare the moles of hydrogen and ammonia:
H₂ : NH₃
3 : 2
1.35 : 2/3×1.35 = 0.89 mol
Mass of ammonia:
Mass = number of moles × molar mass
Mass = 0.89 mol × 17 g/mol
Mass = 15.13 g
They are attracted by the shared pair of electrons. One requires one more electron and the other atom shares one electron with the other, making the atoms come together and stay.
