Global Warming results in rising sea levels as the freshwater from the melted glaciers eventually runs into the ocean.
<h3 /><h3>What is Global Warming ? </h3>
A gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants.
As the climate warms, harmful algal blooms happen more often and become more severe.
As the ocean warms, freshwater glaciers around Earth begin to melt at an unsustainable rate, which results in rising sea levels.
The freshwater from the melted glaciers eventually runs into the ocean.

The molar Concentration of KMnO₄ is 0.000219 M
Concentration is the abundance of a constituent divided by means of the overall extent of an aggregate. numerous styles of mathematical description may be outstanding: mass awareness, molar awareness, variety concentration, and quantity awareness.
y is absorbance
x is the molar concentration of KMnO_4
y = 4.84E + 03x - 2.26E - 01
0.833 = 4.84 * 10⁺⁰³ x - 2.26 * 10⁻¹
1.059 = 4.84 * 10⁺⁰³ x
X = 0.000219 M
Hence, The molar Concentration of KMnO₄ is 0.000219 M

Taking into account the definition of density, the mass of a substance with a volume of 150 cm³ and a density of 1.5 is 225 grams.
<h3>What is density</h3>
Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.
In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance.
Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:
From this expression it can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.
<h3>Mass of the substance in this case</h3>
In this case, you know that:
- Density= 1.5
- Volume= 150 cm³
Replacing in the definition of density:
Solving:
mass= 1.5 ×150 cm³
<u><em>mass= 225 g</em></u>
In summary, the mass of a substance with a volume of 150 cm³ and a density of 1.5 is 225 grams.
