Answer:
Mass = 365.45 g
Explanation:
Given data:
Number of moles of HNO₃ = 5.8 mol
Mass of HNO₃ = ?
Solution:
Formula:
Mass = number of moles × molar mass
Molar mass of HNO₃ = 63.01 g/mol
by putting values,
Mass = 5.8 mol × 63.01 g/mol
Mass = 365.45 g
The Kevlar jacket is only similar to the spiderweb in the arrangement of atoms in molecules of both substances.
<h3>Similarity between spiderweb and a Kevlar jacket</h3>
A spider web refers to the tiny web-like structures that is seen around places where spiders breed. On the other hand the Kevlar jacket is known for its high tensile strength.
The Kevlar jacket is only similar to the spiderweb in the arrangement of atoms in molecules of both substances.

The surface air that flows from these subtropical high pressure belts toward the equator is deflected toward the West in both hemispheres by the Coriolis effect. These winds blow predominantly for the northeast in the northern Hemisphere and from the southwest in the Southern Hemisphere
Answer:
Mass = 2.16 g
Explanation:
Given data:
Number of molecules of F₂ = 3.45 × 10²²
Mass in gram = ?
Solution:
Avogadro number:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ molecules
3.45 × 10²² molecules ×1 mol / 6.022 × 10²³ molecules
0.57× 10⁻¹ mol
0.057 mol
Mass in gram :
Mass = number of moles × molar mass
Mass = 0.057 mol × 37.9 g/mol
Mass = 2.16 g
