Question

0.2 mol NaOH was initially present in 100 ml solution. If it is diluted to 500 ml, then
mole of NaOH in final solution will be​

Answer 1

Answer:

The mole of NaOH will be 0.2

Explanation:

Mole of a substance depends upon its weight and its molecular weight

Therefore,

$\text {Mole}=\frac{\text{Weight in grams}}{Molecular Weight}$

0.2 mole of NaOH will still be 0.2 mole of NaOH be it 100 ml or 500 ml solution. Therefore, the moles of NaOH will not change and it will remain 0.2 moles.
