A scientist makes a solution that contains 80 g of sugar per 200 ml of solution. What is the concentration that describes the solution

By definition, the concentration that describes the solution is 400 .

Solute and solvent are two components of a solution. The solute is the substance (solid, liquid, or gas) that dissolves in the solvent to produce a homogeneous mixture known as a solution.

In the solution, the solute is usually found in a lower proportion than the solvent, while generally, the solvent is the component that is found in the greater proportion in the solution.

The concentration of a solution is the amount of solute (dissolved substance) in an amount of solvent or solution.

There are different ways to express the concentration of a solution.

In this case, the mass of solute per volume of solution is a measure of concentration that is determined by dividing the mass in grams of the solute present in the solution sample by the volume of the sample.

In this case, the solution contains 80 g of sugar per 200 ml (0.2 L, being 1000 mL= 1 L) of solution. Then, the mass of solute per volume of solution can be calculated as:

Solving:

Finally, the concentration that describes the solution is 400 .

a mercury barometer is a device that uses the physical properties of mercury in a tube to measure barometric pressure. mercury barometers are used for : -

1. measurement of atmospheric pressure  

2. determining the altitude of a place

3. weather forecasting

4. calibration and checking of aneroid barometers

5. application in fluid mechanics

6. measurement of pressure in aircrafts

7. surface weather analysis

8. preparation of barographs

9. usage in physical sciences like physics, astronomy & chemistry

10. preparation of aircraft altimeters

characteristics of mercury barometer : -

1.used to define and measure atmospheric pressure.

2.on the average at sea level the column of mercury rises to a height of about 760 mm.

3.this quantity is equal to 1 atmosphere.

4.it is also known as standard atmospheric pressure.

5.a barometer in which the weight of a column of mercury in a glass tube with a sealed top is balanced against that of the atmosphere pressing on an exposed cistern of mercury at the base of the mercury column, the height of the column varying with atmospheric pressure.
