Answer:
2.94 × 10²⁴ molecules
Explanation:
Step 1: Given data
Volume of acetone (V): 360 mL (360 cm³)
Density of acetone (ρ): 0.788 g/cm³
Step 2: Calculate the mass of acetone (m)
Density is equal to the mass of acetone divided its volume.
ρ = m/V
m = ρ × V
m = 0.788 g/cm³ × 360 cm³ = 284 g
Step 3: Calculate the moles corresponding to 284 g of acetone
The molar mass of acetone is 58.08 g/mol.
284 g × 1 mol/58.08 g = 4.89 mol
Step 4: Calculate the number of molecules in 4.89 moles of acetone
We will use Avogadro's number: there are 6.02 × 10²³ molecules of acetone in 1 mole of molecules of acetone.
4.89 mol × 6.02 × 10²³ molecules/1 mol = 2.94 × 10²⁴ molecules

Given 25.43 g of O2 gas, how many liters of gas will you have at STP?
Answer value
Given :
Mass of O₂, m = 25.43 g.
To Find :
How many liters of gas will you have at STP.
Solution :
Molecular mass of O₂, M.M = 2 × 16 gram/mole
M.M = 32 gram/mole
Number of moles is given by :
n = m/M.M
n = 25.43/32 mole
n = 0.79 mole
Hence, this is the required solution.

Carbon-14 is used in radiocarbon dating.
The half-life of carbon-14 is 5.73E3 years. If a sample of carbon-14 has an activity of 0.350 Ci, what is the difference in activities between this sample and the same sample after 1.719E4 years?
Answer:
0.30625 Ci
Explanation:
From the question given above, the following data were obtained:
Half-life (t½) = 5.73E3 years
Original activity (Nₒ) = 0.350 Ci
Time (t) = 1.719E4 years
Difference in activities =?
Next, we shall determine number of half-lives that has elapse. This can be obtained as follow:
Half-life (t½) = 5.73E3 years = 5.73×10³ years
Time (t) = 1.719E4 years = 1.719×10⁴ years
Number of half-lives (n) =?
n = t / t(½)
n = 1.719×10⁴ / 5.73×10³
n = 3
Thus, 3 half-lives has elapsed.
Next, we shall determine the activity after 1.719E4 years. This can be obtained as follow:
Original activity (Nₒ) = 0.350 Ci
Number of half-lives (n) = 3
Activity remaining (N) =?
N = 1/2ⁿ × Nₒ
N = 1/2³ × 0.350
N = 1/8 × 0.350
N = 0.125 × 0.350
N = 0.04375 Ci
Finally, we shall determine the difference in activities. This can be obtained as follow:
Original activity (Nₒ) = 0.350 Ci
Activity remaining (N) = 0.04375 Ci
Difference in activities =?
Difference in activities = Nₒ – N
Difference in activities = 0.350 – 0.04375
Difference in activities = 0.30625 Ci.

The Coriolis effect is the deflection of winds to the right in the Northern Hemisphere and to the left in the Southern Hemisphere because of Earth's rotation. Lesson 2.09 True False
Answer:
True
Explanation:
The Coriolis effect is the deflection of winds to the right in the Northern Hemisphere and to the left in the Southern Hemisphere because of Earth's rotation. This statement is true.
What is Coriolis effect ?Circulating air is deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere as the Earth rotates on its axis. The Coriolis effect refers to this deflection.
Because of the rotation of the Earth, we experience an apparent force known as the Coriolis force. The wind is deflected to the right in the northern hemisphere and to the left in the southern hemisphere as a result of this.
There is no curving of the object's path as measured relative to the Earth's surface because there is no turning of the Earth's surface underneath a horizontally and freely moving object at the equator.
Thus, There is no Coriolis effect because the object's path is straight.

What is the capillary rise of ethanol in a glass tube with a 0.1 mm radius if the surface tension of ethanol is 0.032Jm2 and the density of ethanol is 0.71gcm3
Answer:
Explanation:
Expression for capillary rise is as follows
h = 2T / ρ g r where T is surface tension , ρ is density of liquid and r is radius of capillary tube.
T = .032 J m⁻²
ρ = .71 g / cm³
= 7100 kg / m³
r = .1 x 10⁻³ m = 10⁻⁴ m
h = 2 x .032 / (7100 x 9.8 x 10⁻⁴ )
h = .0092 m
= 9.2 mm .

What is Collision theory?The collision theory states that each and every chemical reaction can occur between particles when the molecules collide each other.
The collision between particles is necessary but it is not sufficient for a reaction to take place. The collisions must be effective.
It is necessary to know the exact nature of an effective collision since this indicates whether particles react with each other and form new products.
According to collision theory, the reaction occur when molecules collide and molecules have sufficient activation energy to cross energy barrier.
Greater the energy, greater will be number of collision. Lesser energy, lesser will be number of collision.
Thus, the given energy diagram shows about the energy required for a reaction to take place.
