Question

If 445 ml of 6.0 M HNO3 is diluted to 2.5 L, what is the molarity of the diluted solution?

Answer 1

  The  molarity  of  dilute  solution   is  calculated  using  M1V1= M2V2   formula
M1 = molarity 1 (  6.0 m)
V1  =  volume  1 ( 445ml)
V2= volume  2 (2.5  x1000  = 2500ml)
M2=  molarity 2 =  ?

M2  is  therefore = M1V1/V2
=  445  ml  x   6.0  M/  2500ml  = 1.07 M
