5.85 g of Nacl is dissolved in 500 ml of water . Calculate the molarity of the solution
Hi numan,
As Molarity= moles of solute/ volume of solution(liters)
M= 5.85*1000/((23+35.5)*500)=0.2M
If you have any further query, feel free to ask.

Hello student,
When we dissolve 5.85g of NaCl in 500 ml of water then the molarity of the NaC l is 0.2M.
Explanation:-
The formula for molarity M is
M = mol v
The moles of sodium chloride is 5.85 58.4 ≈ 0.1 mol
The volume of water is 0.5 l
So
M = mol v = 0.1 0.5 = 0.2 M
Cheers!
