<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

As far as I know, may be wrong :When pressure is multiplied by a number, the gas volume also gets multiplied by the same number. So, the answer can be found by doing: (3.4/1.97)(12), and the answer is about 20.71.
Answer:
The mouth uses both mechanical and chemical digestion. Mechanical digestion involves physically breaking down the food into smaller pieces (using the jaw/teeth). However, chemical digestion then takes over and starts breaking down the food into simpler nutrients that can be used by the cells using saliva, which is naturally made within the mouth.
Hope this helps you! Have a great day! :D
D= 0.10125kg/m^3
EXPLAINATION
Density =mass/volume
D= 226.8/20 x 8 x 14
D=226.8/2240
D= 0.10125kg/m^3
Hope it was helpfull!!
The solubility of solid substances generally increase as temperature increases. The solubility of gaseous substances generally decrease as temperature increases.
