4 0

Answer:

5 g of H₂ are contained in the vessel

Explanation:

A typical excersise of conversion:

We determine molar mass of H₂.

This is a dyatomic molecule, as molar mass of H is 1g/mol, molar mass of H₂ will be 2g/mol.

Let's make the conversion of units:

2.5 mol . 2g/mol = 5 g

5 g of H₂ are contained in the vessel

Observation of experiment and intervention in newton's optics. newton followed the principle of light through prisms and the rays transmitted through them as a part of his observation. Various properties of light and its characteristics were exposed.

Explanation:

  • Newton's investigation of light was based on prisms, lenses and optical rays.
  • He stated that lights differing in colour also differed in degrees of re-frangibility.
  • To support his theories newton employed "Proof by experiments" method. Each method was designated in revealing a specific property of light.
  • A phenomenon known as Newton rings were discovered by newton.
