<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
Answer:
No because it's located inside the nucleus of the atom
hope this helps
have a good day :)
Explanation:
Answer:
Ayn npo!!!!!!!!!!!!!!!!!!!!!!
Calcium=Ca2+
Carbonate=(CO3)2-
Therefore it is composed of Calcium, Carbon and Oxygen.
Answer:
Explanation:
1. Write down the balanced equation
2. Use molar mass of O2 (32g/mol) divided by the given mass to derive the amount of mols
3. multiply the answer by 2/3 (divide by 3 then multiply by 2), to ensure the mols are in correct proportion
4. Use given molar mass and multiply it by the amount
5. Make sure to use proper significant digits (3 in this case) and units :)
