Answer:
The final volume will be 3.39 liters
Explanation:
P1V1/T1 = P2V2/T2
P1 = 3 atm
T1 = 19( degrees celsius) + 273 = 292 K
V2 = TO BE DETERMINED
P2 =1 atm
T2 = 22( degrees celsius) + 273 = 295 k
P1V1/T1 = P2V2/T2
V2 = P1V1T2/P2T1 = (3)(1.12)(295)/(1)292) = 3.39 Liters
Answer:
6.02 × 10²³ atoms.
Explanation:
According to the Avogadro number, the one mole of any substance have 6.02 × 10²³ atoms.
The number 6.02 × 10²³ is called Avogadro number. it is the number of atoms, ions or molecules in one gram atoms of element, one gram ions of substance or one gram molecules of a compound.
For one mole of magnesium.
24.305 g of Mg = 1 mole of magnesium = 6.02 × 10²³ atoms of magnesium.
Other example includes:
18 g of water = one mole of water = 6.02 × 10²³ molecules of water.
23 g of sodium = one mole of sodium = 6.02 × 10²³ atoms of sodium.
We can confirm that in a roller coaster, kinetic and potential energy in the car decreases at each successive hill because of the force of gravity which converts potential energy into kinetic energy.
<h3>What are potential and kinetic energy?</h3>
- Potential energy is referred to as <em><u>positional energy</u></em>.
- This means that the object in question gains energy based on its position relative to others.
- Kinetic energy is the energy of movement.
- Gravity causes the roller coaster to fall, losing potential energy.
- This causes it to gain all of the potential energy as kinetic energy.
- Once at the bottom, the coaster no longer moves and thus loses the kinetic energy as well.
Therefore, we can confirm that gravity is the force that causes the shift from potential energy to kinetic energy and thus causes them both to decrease after each successful hill in the roller coaster.

Answer:
Fatty acid
Explanation:
A fatty acid is a carboxylic acid with a long chain of 12 or more carbons.
If the molecule has no other distinguishing features, the compound is hexacosanoic acid, CH₃(CH₂)₂₄COOH.
We will use this formlula: Mass in grams = Number of moles x Molecular mass of 1 mole.
Since, we know the avagadro number is 6.02 x 10²³, we only have two unknown values left which are the molecular mass of CH3OH and its mole.
Molecular Mass: C = 12, H= 1, O = 16, since we have C=12, H4 = 4, O = 16, we will add them up: 12 + 4 + 16 =32
We know that one mole of anything = 6.02 x 10²³.
So we will use this formula to find the mole of methanol: Number of moles = Number of molecules / Avagadro number
Number of moles of CH3OH = (9.79 x 10^24)/6.02 x 10²³) = 16.263 moles.
Now we know that the molecular mass = 32 and the mole is = 16.263.
Now we can find its mass by using this formula: <span>Mass in grams = Number of moles x Molecular mass of 1 mole.
</span>
Mass in grams = 16.263 x 32 = 520g
