Answer: strong nuclear forces and electrostatic forces of repulsion
Explanation:
Answer:
No
Explanation:
The solubility of a solid in water refers to the amount of that solid that dissolves in water.
It is not possible to calculate the solubility of the solid because the student threw away the first precipitate that formed. We already have the volume of water, but having lost some mass of precipitate, it has become impossible to accurately determine the solubility.
Hence the answer provided above.
<h3>Mol of methanol =12.35</h3><h3>Further explanation</h3>
Mole itself is the number of particles contained in a substance
1 mole = 6.02.10²³ particles
Mole : the ratio of the amount of substance mass and its molar mass

Molarity is a way to express the concentration of the solution
Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution

Molar concentration of methanol=24.7 M
Volume of solution = 500 ml = 0.5 L
