Question

Commercial concentrated ammonia NH3 is 14.5 M. How many mL of concentrated ammonia would be needed to prepare 1.00 L of 2.00 M NH3?

Answer 1

Answer #1

initial fianal

M1 = 14.5M M2 = 2M

V1 = V2 = 1L

form dilution law

M1V1 = M2V2

V1 = M2V2/M1

= 2*1/14.5

= 0.138L

The volume of concentrated ammonia = 0.138L = 138ml >>>>>answer

Answer 2
