Answer:
The answer is
<h2>2.55 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass = 416 g
volume = final volume of water - initial volume of water
volume = 523 - 360 = 163
volume = 163 mL
The density is

We have the final answer as
<h3>2.55 g/mL</h3>

Answer:
Potassium
Explanation:
In group one of the periodic table both the melting and the boiling points usually decrease down the group.
Now, down the group, it's lithium that comes first, then sodium, then potassium.
Thus, among the 3, potassium is furthermost down the group by virtue of the factor it has the highest atomic number.
Therefore, we can say that potassium has the lowest boiling point among the 3.
Answer: an arithmetical multiplier for converting a quantity expressed in one set of units into an equivalent expressed in another.
Explanation:
D sublevel because the s sublevel has one orbital, the p sublevel has three orbitals, the d sublevel has five orbitals, and the f sublevel has seven orbitals. In the first period, only the 1s sublevel is being filled.
