Out of the options, glass is the least fluid. The proof of this also lies in the fact that glass is the most difficult to melt out of all of the mentioned substances, and melting point gives us a rough estimate of the strength of intermolecular forces.

Answer: -
280mg
Explanation: -
The chemical formula is C14H18N2O5
Molar mass of the compound = 12 x 14 + 1 x 18 + 14 x 2 + 16 x 5 = 294 gram
Number of nitrogen atoms present in the formula = 2
Mass of nitrogen present= 14 x 2 = 28 gram
Thus 294 gram of the compound has 28 gram.
Hence 2.95grams of the compound has (28 gram x 2.95 gram / 294 gram)
= 0.28 gram
= 280 mg
Thus 280 mg of nitrogen is present in 2.95 grams of C14H18N2O5
When 32.0 g of F₂ react with enough N₂, 39.86g of NF₃ are formed.
<h3>What is stoichiometry?</h3>
Stoichiometry is the study of the quantitative relationships or ratios between two or more substances undergoing a physical change or chemical change.
Let's consider the following balanced equation.
N₂ + 3 F₂ ⇒ 2 NF₃
To calculate the mass of NF₃ formed from 32.0 g of F₂, we need to consider the following relationships.
- The molar mass of F₂ is 38.00 g/mol.
- The molar ratio of F₂ to NF₃ is 3:2.
- The molar mass of NF₃ is 71.00 g/mol.

When 32.0 g of F₂ react with enough N₂, 39.86g of NF₃ are formed.
