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
Answer:
Why science communication is important? In the world we live in, not only does pursuing science matter but communicating about it effectively is important as well. Communicating about science is crucial, whether we communicate about it online or face to face, communication about the scientific facts is vital for the scientific community. This is especially important now when many question scientific methods, research, and results. We are not only talking about communication about science between academics, scientists and corporations, but we are also talking about the gap between the scientific world and non-scientific community.
