Rudiy27

Answer:

two north poles and two south poles

Explanation:

A single magnet has a north pole and a south pole. If it is broken into two pieces, then each of the two pieces will have a north pole and a south pole.

No matter how many times or into how many pieces a magnet is broken, the resulting pieces will have two poles each.

One of the uses of methanol (CH3OH) in dilute form is as a windshield washer antifreeze. In pure form, methanol has a molar conc
Dovator [93]
<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

\large{\boxed{\boxed{\bold{mole=\frac{mass}{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

\large{\boxed {\bold {M ~ = ~ \frac {n} {V}}}

Molar concentration of methanol=24.7 M

Volume of solution = 500 ml = 0.5 L

\tt mol=M\times V\\\\mol=24.7\times 0.5\\\\mol=12.35
