Question

3 moles of NaOH solution has a volume of 1 litre then find molarity of solution ( given~ density of solution = 2g \ ml and vol solution = vol of solvent)​

Answer 1

Answer:

ans is 3000 M

Explanation:

formula for molarity (M) =moles of solute /volume of solution in ml

so 3g x 1000/1 so ans is 3000 (M)

Answer 2

Answer:

3 M Sodium hydroxide Solution

Explanation:

3 M Sodium hydroxide Solution  

Molar mass of NaOH is 40 g/mol. 3 mol of NaOH has 120 g.  

Molarity (M) = Mass of solute (g) / Molar mass of Solute (g/mol-1) * 1 / volume of solution (L)  

Molarity (M) = Moles of solute (mol) / volume of solution (L)

Molarity (M) = Moles per liter  

Molarity of Sodium Hydroxide = 3 mol per liter  

So, 3 mol / 1 L = 3 M Sodium hydroxide Solution
