Answer:
3.72 mol Hg
General Formulas and Concepts:
<u>Chemistry - Atomic Structure</u>
- Reading a Periodic Table
- Using Dimensional Analysis
- Density = Mass over Volume
Explanation:
<u>Step 1: Define</u>
D = 13.6 g/mL
54.8 mL Hg
<u>Step 2: Identify Conversions</u>
Molar Mass of Hg - 200.59 g/mol
<u>Step 3: Find</u>
13.6 g/mL = x g / 54.8 mL
x = 745.28 g Hg
<u>Step 4: Convert</u>
<u />
= 3.71544 mol Hg
<u>Step 5: Check</u>
<em>We are given 3 sig figs. Follow sig fig rules and round.</em>
3.71544 mol Hg ≈ 3.72 mol Hg
Answer:
B. The collisions release heat, which results in the heating and subsequent melting, sinking, and rising of materials.

Answer:
D
Explanation:
The proberties of the substances that are produced are different from the properties of the original substances.
Answer:
The answer is
<h2>2.0 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass of block = 10 g
volume = final volume of water - initial volume of water
volume = 25 - 20 = 5
volume = 5 mL
The density of the block is

We have the final answer as
<h3>2.0 g/mL</h3>
