Pavel [41]
NH₃:

N = 8*10²²
NA = 6.02*10²³

n = N/NA = 8*10²²/6.02*10²³ ≈ 1.33*10⁻¹=0.133mol

O₂:

N=7*10²²
NA = 6.02*10²³

n = N/NA = 7*10²²/6.02*10²³ = 1.16*10⁻¹=0.116mol

Romashka-Z-Leto [24]

Answer:

New experimental methods

Technological inventions

Explanation:

A scientific theory is usually not based on speculation. Scientific theories must have a solid empirical basis.

However, experimental methods are limited to the caliber of equipments available at the time in which a theory is formulated. With advancing years, more technological sophistication leads to the invention of new instruments and ultimately, the development of new experimental methods.

These innovations are likely to alter existing scientific theories as new evidences emerge, hence the answer.
