2 moles of sodium chloride are dissolved in 8 liters of water. What is its molarity (M) ?
otez555 [7]

Answer:

0.25M

Explanation:

Since molarity is defined as the amount of substance in 1 liter of a solution, and amount in chemistry refers to the number of moles, molarity can be found using the equation below:

Molarity= number of moles ÷ volume in liters

Given: number of moles= 2

Volume= 8L

∴ Molarity of NaCl

= 2 ÷8

= 0.25M

Alchen [17]

Answer:

Explanation:

The hydrostatic pressure is defined as the pressure that is exerted by a fluid at equilibrium at a given point within the fluid, due to the force of gravity, the formula is:

P = ρgh + P₀

Where:

ρ is density (1020kg/m³)

g is gravity (9,8m/s²)

h is depth (150m)

P₀ is the atmspheric pressure (101325 Pa)

Replacing, P = 1'600'725 Pa

I hope it helps!
