1 mole of propane = 6.02*10^23 propane molecules
<span>2.12 moles of propane = 1.27624*10^24 propane molecules </span>
Answer:
156 mL will be the new volume of the shape
Explanation:
First of all, we need to convert the Torr to atm.
1220 Torr . 1 atm / 760 Torr = 1.60 atm
When the temperature remains constant, it is satisfied that the volume is modified indirectly proportionally.
Pressure is increased, then volume decreases
Pressure is decreased, then volume increases
P₁ . V₁ = P₂ . V₂
0.768 atm . 325mL = 1.60 atm . V₂
V₂ = 0.768 atm . 325mL / 1.60 atm → 156 mL
Molar mass :
HC₂H₃O₂ = 1 + 12*2 + 1 * 3 + 16 * 2 = 60 g/mol
1 mole <span>HC₂H₃O₂ -------------- 60 g
</span>1.26x10-⁴ mole ----------------- mass
mass = 1.26x10-⁴ * 60
mass = 0.00756 g of <span>HC₂H₃O₂</span>
hope this helps!
I don't really know but I'm guessing that by doing 450 divided by 12.6 you would get 35.73 grams of water
Answer:
a. Are miscible because each can hydrogen bond with the other.
Explanation:
Both ethanol and water are miscible. The reason why they can both mix freely is due to the hydrogen bonds that will form between their molecular structure.
Hydrogen bonds are special dipole-dipole attraction between polar molecules in which hydrogen atoms are directly joined to an electronegative atom.
Ethanol has an hydroxyl group which will bond to form an intermolecular bond with the oxygen and hydrogen on the water molecule. This attraction makes them miscible.
