Question

What is the resulting molarity of solution when 2g of NaOH is dissolved in 500 ml of water? (molar mass of NaOH=40.)?

Answer 1

`"Molarity"` `=` `0.10*mol*L^-1` with respect to `NaOH`.

Explanation:

`"Molarity"` `=` `"Moles of solute"/"Volume of solution"`

`"Molarity"` `=` `(2*g)/(40.0*g*mol^-1)xx1/(500*mLxx10^-3*L*mL^-1)`

`=` `??mol*L^-1`.
