[tex]n = \frac{N}{L} \\[/tex]
From the question
N = 4.36 × 10^25 molecules
We have
[tex]n = \frac{4.36 \times {10}^{25} }{6.02 \times {10}^{23} } \\ = 72.425249...[/tex]
We have the final answer as

This diagram shows a marble with a mass of 3.8 grams (g) that was placed into 10 milliliters (mL) of water. Using the formula D = MV, what is the density of the marble? 0.29 g/cm 3 0.38 g/cm 3 1.27 g/cm 3 2.63 g/cm 3
Answer:
1.27 g/cm^3
Explanation:
Density of a body is defined as mass/volume. We can easily read off the mass of the marble from the image.
Mass of the body = 3.8 grams
Volume of the body = 3 ml
Density of the body; mass/volume
D= 3.8/3
D= 1.27 g/cm^3

Which subatomic particle has the least mass?
electron
proton
neutron
positron
The atoms of an element are made of subatomic particles that include electrons, protons, neutrons, positrons, etc. The electron has the least amount of relative mass. Thus, option A is correct.
What are subatomic particles?Subatomic particles are the smallest unit that makes a whole atom. The positively charged particle, a proton has a relative mass of 1.672 × 10⁻²⁷ kg and is the same as the neutron particle.
Though the neutrons lack any charge and are present in the nucleus with protons. The other particle called electrons is negative in charge with a relative mass of 9.1 × 10⁻³¹ Kg.
The electron is outside the nucleus in the shells. The positrons have the same mass as an electron but carry an opposite charge and act as antimatter.
Therefore, option A. the electrons have the least amount of mass in an atom.

Explanation:
how does the latitude affect the temperature
Answer:
Latitude is one of the main factors affecting temperature. Latitude is the measurement of the distance of a location on the Earth from the equator. ... At the Equator, the Sun's rays strike the Earth at a right angle, which makes the heat more intense and concentrated over a small area.
Explanation:
As latitude increases, the temperature falls, and vice versa. Generally, around the world, it gets warmer towards the equator and cooler towards the poles.

are all metals magnetic?
✅Magnetic materials are always made of metal, but not all metals are magnetic. Iron is magnetic, so any metal with iron in it will be attracted to a magnet. Steel contains iron, so a steel paperclip will be attracted to a magnet too. Most other metals, for example aluminium, copper and gold, are NOT magnetic.

How can one kg of iron melt more ice than 1 kg lead at 100 °C
Answer:
Due to the specific heat capacity of iron, 0.444 J/(g·°C), is more than the specific heat capacity for lead, 0.160 J/(g·°C)
Explanation:
The given parameters are;
The metals provided to melt the ice and their temperature includes;
One kg (1000 g) of iron;
Specific heat capacity = 0.444 J/(g·°C)
Temperature = 100°C
1 kg (1000 g) of lead
Specific heat capacity = 0.160 J/(g·°C)
Temperature = 100°C
Therefore, the heat provided to the ice of mass m, and latent heat of 334 J/g at 0°C by the metals are as follows;
For iron, we have;
ΔQ = Mass × Specific heat capacity × Temperature change
ΔQ[tex]_{iron}[/tex] = Heat obtained from the iron by the ice
ΔQ[tex]_{iron}[/tex] = 0.444 m × 1000 × (100 - 0) = 44400 J
Heat absorbed by the ice for melting, H[tex]_l[/tex] = Heat obtained from the iron
∴ Heat absorbed by the ice for melting, H[tex]_l[/tex] = Mass of ice × Latent heat of ice
H[tex]_l[/tex] = Mass of ice × 334 J/g = 44400 J
Mass of ice melted by the iron = 44400 J/334 (J/g) ≈ 132.9 g
Mass of ice melted by the iron ≈ 132.9 g
For lead, we have;
ΔQ = Mass × Specific heat capacity × Temperature change
ΔQ[tex]_{lead}[/tex] = Heat obtained from the iron by the ice
ΔQ[tex]_{lead}[/tex] = 0.160 m × 1000 × (100 - 0) = 16000 J
Heat absorbed by the ice for melting, H[tex]_l[/tex] = Heat obtained from the iron
∴ Heat absorbed by the ice for melting, H[tex]_l[/tex] = Mass of ice × Latent heat of ice
H[tex]_l[/tex] = Mass of ice × 334 J/g = 16000 J
Mass of ice melted by the lead = 16000 J/334 (J/g) ≈ 47.9 g
Mass of ice melted by the lead ≈ 47.9 g
Therefore, mass of ice melted by the iron, approximately 132.9 g, is more than mass of ice melted by the lead, approximately 47.9 g.
How could Armando use this model to test the idea that very steep hills lead to narrow, deep rivers?
Armando used this model to test the idea that you can modify the table legs using a certain sand size and record the results to test the hypothesis that extremely steep hills lead to narrow, deep rivers.
What is a model?A model is an artificial representation of an object or a process. Models are used to show the process or things that are very big and can not be understood by the actual thing.
Sand, granite, mud, and other objects from the earth are carried away by the energy of the rushing water, along with water-soluble substances like limestone.
Thus, depending on how quickly a river flows, it has more or less. The ability to remove more material, as the river runs more quickly when it is narrow than large, leads to the development of a deep and narrow river.
