A chemist prepares a solution of copper(II) fluoride by measuring out of copper(II) fluoride into a volumetric flask and filling

Simora [160]

The question is incomplete, here is the complete question.

A chemist prepares a solution of copper(II) fluoride by measuring out 0.0498 g of copper(II) fluoride into a 100.0mL volumetric flask and filling the flask to the mark with water.

Calculate the concentration in mol/L of the chemist's copper(II) fluoride solution. Round your answer to 3 significant digits.

Answer: The concentration of copper fluoride in the solution is $4.90\times 10^{-3}mol/L$

Explanation:

To calculate the molarity of solute, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}$

We are given:

Given mass of copper (II) fluoride = 0.0498 g

Molar mass of copper (II) fluoride = 101.54 g/mol

Volume of solution = 100.0 mL

Putting values in above equation, we get:

$\text{Molarity of copper (II) fluoride)=\frac{0.0498\times 1000}{101.54\times 100.0}\\\\\text{Molarity of copper (II) fluoride}=4.90\times 10^{-3}mol/L$

Hence, the concentration of copper fluoride in the solution is $4.90\times 10^{-3}mol/L$

Some areas of the Earth receive more solar radiation than others. Which of the following results from the Sun's uneven heating o

STatiana [176]

Some areas of the Earth receive more solar radiation than others and this Sun’s uneven heating of the Earth result in 

i. Climate

ii. Weather

iii. Ocean currents

Further Explanations:

Earth receives varied amount of solar radiation in its different parts. The situation is due to the orbicular shape of the Earth and inclination of the sun during different time of the year. We can see one such example that, during June sun is overheard Tropic of cancer and during September it is overhead Tropic of Capricorn. Because of the inclination,different regions of the Earth experience different climate at the same span of time. This unevenness results in the following phenomenon:

i. Climate:Climate is a continuing average weather condition of a place. Some of the climatological variables commonly measured to determine the climate temperature, moistness, atmospheric pressure, current of air, and precipitation.

ii. Weather: It is defined as the state of atmosphere, describing the degree of heat or coldness, wetness or aridness, calm or stormy. It also refers to daily temperature and rainfall activities.

iii. Ocean Current: It is more or less perpetual or continuous engaged movement of oceanic water flowing on the Earth’s oceans. The current gets created as the resultant of geological forces acting on the oceanic surface.
