Question

8.5 grams of ammonia are dissolved to form 4L aques solution. calculate the active mass.​

Answer 1

Answer:

active mass = (wt/Mw) x (1000/V)

wt = weight of solute

Mw = molecular weight of solute

V = volume of solution in ml

so

active mass = (8.5/17) x (1000/250)

active mass = 0.5 x 4 = 2 M
