Mathematics

In fact, this problem belongs to the chemistry section.  Recall that many other sciences require mathematical calculations.  The problem will belong to Mathematics only if no knowledge of other sciences are required to solve the problem.

Solubility for the given substances is measured in grams per 100 g of water at a particular temperature (20 deg.C).
This means that the mass (assumed to be the solute) will not change the solubility, just the minimum quantity of solvent (water) will.
Thus the solubility of sodium chloride will remain L=36 g/100g H2O for any quantity of solute.  Similarly, the solubility of lead nitrate will remain as K=54 g/100 g H2O.

The reason that they remain constant is because the quantity of solvent (water) is fixed at 100 g.  Varying amount of solute will affect the quantity of solvent required, but not the solubility.
I'll leave it to you to calculate the difference between K & L.

Write the simplified form of -64^1/3
GREYUIT [131]

Answer:

-4

Step-by-step explanation:

<em>Factor by the numbers from left to right.</em>

<em>64^\frac{1}{3}</em>

<em>64=4^3</em>

<em>(\frac{4}{3})^\frac{1}{3}=4^3^*^\frac{1}{3}=4</em>

<em>It changes to positive to negative.</em>

<em>-4</em>

<em>-4 is the correct answer.</em>

Lee scored 91 points on a math testOn the next test, she scored 13 fewer pointsOn the third test, she scored 92What is the diffe
max2010maxim [7]

Answer:

14 points

Step-by-step explanation:

The second test Lee did was 13 points fewer than the first test, which was 91 points, so the second test's score is 91 - 13 = 78 points.

The third test had the score of 92, so this is the highest score, and the lowest score is the second one: 78 points.

The difference between Lee's highest and lowest scores is:

92 - 78 = 14 points
