How many mL of concentrated ammonia (14M) should be diluted to 250 mL to make a 0.75 M NH3 solution?
Answered by bobpursley
you are diluting it 14/.75= 14*4/3= 18 2/3 times. That means one part original stuff, 17 2/3 parts water.

what is one part? 250ml/(18.6666)=13.393 ml

so 13.392 ml of 14M conc ammonia
and 17 2/3 x 13.392=236.607ml water.
