A quantitative observation is not necessarily more useful than a non-quantitative one. However, quantitative observations do allow one to find trends.
(a), the sun rising is a non-quantitative observation.
(b), knowledge of the numerical relationship between the weight on the Moon and on Earth, is a quantitative observation.
(c), watching ice float on water does not involve a measurement; therefore, it must be a qualitative observation.
(d) the fact that we know that the water pump won’t work for depths more than 34 feet makes it quantitative. Again, seeing numbers is a giveaway that it’s a quantitative <span>observation. Quantitative is where you deal with numbers.</span>

Answer:
0.015 M
Explanation:
Let's consider the solution of silver (I) sulfate.
Ag₂SO₄(s) ⇄ 2 Ag⁺(aq) + SO₄²⁻(aq)
In order to find the solubility (S) of silver (I) sulfate, we will use an ICE chart.
Ag₂SO₄(s) ⇄ 2 Ag⁺(aq) + SO₄²⁻(aq)
I 0 0
C +2S +S
E 2S S
The solubility product (Ksp) is:
Ksp = 1.4 × 10⁻⁵ = [Ag⁺]².[SO₄²⁻] = (2S)².S = 4S³
S = 0.015 M
