Boyle's law states describes the relationship between volume and pressure for a given mass of gas and it aided our understanding of breathing.
Boyle's law states that, the volume of a given mass of gas is inversely related to its pressure at as long as the temperature is constant .
This means that, as the volume of a given mass of gas increases, its pressure decreases.
As the lungs expand during breathing, the volume of air in them increases as the pressure of air inside the lungs decreases.

Answer:
0.4444 g/cm³ ≅ 0.44 g/cm³ (2 significant figures).
Explanation:
<em>d = m/V,</em>
where, d is the density of the material (g/cm³).
m is the mass of the material (m = 28 g).
V is the volume of the material (V = 63.0 cm³).
<em>∴ d = m/V </em>= (28 g)/(63.0 cm³) = <em>0.4444 g/cm³ ≅ 0.44 g/cm³ (2 significant figures).</em>
Answer:
Mass of HCl = 73 g
Explanation:
Given data:
Mass of hydrogen = 2 g
Mass of HCl = ?
Solution:
First of all we will write the balance chemical equation:
H₂ + Cl₂ → 2HCl
Number of moles of hydrogen = 2 g/ 2g/mol
Number of moles of hydrogen = 1 mol
Form balanced chemical equation compare the moles hydrogen with HCl.
H₂ : HCl
1 : 2
Mass of HCl:
Mass of HCl = number of moles × molar mass
Mass of HCl = 2 mol × 36.5 g/mol
Mass of HCl = 73 g
