Explanation:
magnesium can be used for the construction as only when the metal is divided into fine pieces or as a thin sheet, magnesium will burn rapidy.
Yes, we can dissolve 35 moles of KMnO₄ into 500 mL of water to give a molarity of 70 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 molarity </h3>
- Mole of KMnO₄ = 35 moles
- Volume = 500 mL = 500 / 1000 = 0.5 L
Molarity = mole / Volume
Molarity = 35 / 0.5
Molarity = 70 M
