Question

500 ML of 0.2 molal naoh solution is required to utilize 500 ml of X-M h2so4 solution. then find the value of x​

Answer 1

Answer:

Molarity (M) : The number of moles of a solute dissolved in 1 L (1000 ml) of the solution is known as the molarity of the solution.

Molarity of a solution

(M)=molar mass of solutemass of solute×volume of solution in mL1000

∴0.2=40w×5001000

so w=4gm.

Amount of sodium hydroxide present in 500ml of 0.2M solutions is 4 gm.
