#### 4L of 0.02 M aqueous solution of Nacl was diluted by adding one litre of water. The molarity of the resultant  solution  is   Option 1) 0.004 Option 2) 0.008 Option 3) 0.012 Option 4) 0.016

As learnt in

Molarity -

-

Number of moles of NaCl = 4 x 0.02 = 0.08

Total final volume = 5 L

M = 0.08 / 5 = 0.016 M
