Question

if i add water to 100ml of a 0.15 m naoh solution until the final volume is 150 ml,what will the molarity of the diluted solution be?

Answer 1

Answer:

0.1 mol×L

Explanation:

Concentration= MOLES of SOLUTE / Volume of SOLUTION

So all we need to is to calculate the one quantity; Volume of SOLUTION has been specified to be 150 ml

So, MOLES of SOLUTE

x 100 x 10-L = ??mol; this was our starting solution.

And final CONCENTRATION=

0.15 . mol. 5 x 100 x 10-3L/

= 0.15 mol · L-1 150 x 10 3

=0.1 mol · L

Answer 2
