Answer:
375 g
Explanation:
Let the total mass of the solution = x g
Given that the mass of NaOH in the solution = 15.0 g
Thus, mass of the solvent = x - 15.0 g
Given that the mass % of the solution = 4 %
So,

So,

<u>Mass of the solution = 375 g</u>
In the case of bodies with substantial atmospheres, such as Earth's atmosphere, the exosphere<span> is the uppermost layer, where the atmosphere thins out and merges with interplanetary space. It is located directly above the thermosphere.</span>
Answer:
12
Explanation:
pOH = -log(1.0 x 10^-2) = 2
pH = 14 - pOH
pH = 14 - 2 = 12
Matter<span> takes up space. You can put it in a container. While gases, liquids, and solids take up space, </span>light<span> and </span>heat<span> do </span>not<span>. Usually </span>matter<span> and energy are found together, so it can be tricky to distinguish between them. Hope this helps!!</span>
