Question

Calculate the volume of 14.3m NH3,, solution needed to prepare 1L of 0.1 M solution

Answer 1

in order to make this dilution use this formula to simpilfy things:
m (a)* volume (a) = m (b)* volume (b)
 in this case m is in moles/L and volume is in L
14.3 moles/L*?=o.1 moles/L*1L
?=0.1/14.3
?=0.007L which is 7mL in total volume o 1L
