During the laboratory work, the student calculated the pressure of sulfuric acid at the bottom of the beaker.

During the laboratory work, the student calculated the pressure of sulfuric acid at the bottom of the beaker. It turned out to be equal to 2250 Pa. The height of the acid column is 12.5 cm. Is the student right?

Given:

P = 2250 Pascal – pressure of sulfuric acid at the bottom of the beaker, received by the student during laboratory work;

h = 12.5 centimeters = 0.125 meters – the height of the sulfuric acid column;

g = 9.8 Newton / kilogram – acceleration of gravity;

ro = 1836 kilograms / cubic meter – density of sulfuric acid.

It is required to determine whether the student made the correct calculations.

Let’s calculate the pressure of a column of sulfuric acid at the bottom of the beaker:

P1 = ro * g * h = 1836 * 9.8 * 0.125 = 17992.8 * 0.125 = 2249.1 Pascal (approximately equal to 2250 Pascal).

Since P1 = P (2249.1 is approximately equal to 2250), the student performed all the calculations correctly.

Answer: The student performed the calculations correctly.
