Question

If 2gram of naoh is present in 200ml of its solution its molarity

Answer 1

We know that molarity Is given by
M = moles of solvent / volume of solution

Here given mass of NaOH = 2 gram
molar mass of NaOH = 40 g
Thus no of moles of NaOH = 2/40 => 1/20 moles

Now molarity =
$\frac{1}{200 \times 20} \times 1000$
=> 1
HENCE MOLARITY OF THE SOLUTION IS 1 M
