If the pressure at a depth of 8 ft below the surface of a stagnant fluid is 3.5 psi, what will the pressure of the liquid be at a depth of 48 ft below the surface?

Answer : The pressure of the liquid at depth of 48 ft below the surface of fluid is, 21 psi.

Explanation : Given,

The pressure of the liquid at depth 8 ft = 3.5 psi

Now we have to calculate the pressure of the liquid at depth 28 ft.

According to the question,

As, the depth of 8 ft below the surface of a stagnant fluid has pressure = 3.5 psi

So, the depth of 48 ft below the surface of a stagnant fluid has pressure =

Therefore, the pressure of the liquid at depth of 48 ft below the surface of fluid is, 21 psi.

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles
