Question

calculate ph of a solution concentration is 2g of sodium hydroxide dissolved in 500ml solution at 25 degree celcius​

Answer 1

Answer:

Molarity = 0.10⋅mol⋅L−1 with respect to NaOH.

Explanation:

Molarity = Moles of soluteVolume of solution

Molarity = 2⋅g40.0⋅g⋅mol−1×1500⋅mL×10−3⋅L⋅mL−1

= ??mol⋅L−1.
