Question

calculate molarity of 240 g
of NAOH in 200ml .​

Answer 1

Answer:

weight of the solute = 2.46gm

molar mass of the solute = 40g/ml

volume of the solution = 100ml

so,Molarity =

V×M

2

1000×w

2

= 100×40

so molartity = 0.615M

so answer is 0.615

ans is C

Answer 2

Answer:

For a solution of 240g of NaOH in 200mL of water molarity is 30M

Explanation:

Given mass of solute (i.e.,NaOH),w₂ = 240g

volume of solvent(i.e., water),V - 200mL

Molecular mass of the solute - 40

Molarity = [Given mass/Molecular mass] [1000/volume of the solute]
