1 Answer
We have approx.
Explanation:
We are given a concentration in terms of molality.
And thus....................................
And thus...........
Do you see what I have done here? We were given the molality, and then we used this value to calculate the percentage by mass. The total mass included the sulfuric acid and the water...Quite clearly, we also had to KNOW definitions of
