The concentration of the bromine solution, given the data is 0.04 M
<h3>What is molarity? </h3>
Molarity is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:
Molarity = mole / Volume
<h3>How to determine the mole of bromine molecule (B₂)</h3>
- Mass of B₂ = 1.6 g
- Molar mass of bromine molecule (B₂) = 80 × 2 = 160 g/mol
- Mole of bromine molecule (B₂) = ?
Mole = mass / molar mass
Mole of bromine molecule (B₂) = 1.6 / 160
Mole of bromine molecule (B₂) = 0.01 mole
<h3>How to determine the molarity of the bromine solution</h3>
- Mole of bromine molecule (B₂) = 0.01 mole
- Volume of solution = 250 cm³ = 250 / 1000 = 0.25 L
- Molarity bromine solution =?
Molarity = mole / Volume
Molarity bromine solution = 0.01 / 0.25
Molarity bromine solution = 0.04 M
Thus, molarity of the bromine solution is 0.04 M

This force is known as gravitational pull (gravity). This is caused by an uneven balance between mass and energy, creating a forced circular motion known as "orbit".
