Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.

Question

### Measurement Operations

**Task:** Add or subtract the following measurements. Be sure each answer you enter contains the correct number of significant digits.

#### Problems:

1. **Addition:**
\[
14.820 \, \text{mL} + 3.97 \, \text{mL} = \quad \underline{\quad} \quad \text{mL}
\]

2. **Subtraction:**
\[
9.77 \, \text{mL} - 6.9 \, \text{mL} = \quad \underline{\quad} \quad \text{mL}
\]

3. **Addition:**
\[
2.70 \, \text{mL} + 6.800 \, \text{mL} = \quad \underline{\quad} \quad \text{mL}
\]

#### Visual Aids:

Next to the problems, there is a control panel with the following elements:
- A square checkbox and a square checkbox labeled $\times 10$.
- A grey bar with a large "X" symbol and a circular arrow, which likely represents cancel/reset options.

Be sure to apply the correct rules of significant figures for each operation.

### Notes on Significant Figures:
- **Addition/Subtraction:** The result should have the same number of decimal places as the measurement with the least number of decimal places.

#### Examples:
- For 14.820 mL + 3.97 mL, the result should be rounded to the hundredths place (two decimal places).
- For 9.77 mL - 6.9 mL, the result should be rounded to the tenths place (one decimal place).
- For 2.70 mL + 6.800 mL, the result should be rounded to the hundredths place (two decimal places).

Hexane (C6H14, density = 0.766 g/cm3), perfluoro-hexane (C6F14, density = 1.669 g/cm3), and water are immiscible liquids; that is, they do not dissolve in one another. You place 10 mL of each in a graduated cylinder, along with pieces of high-density polyethylene (HDPE, density = 0.97 g/cm3), polyvinyl chloride(PVC, density = 1.36 g/cm3), and Teflon (density = 2.3 g/cm3). None of these common plastics dissolves in these liquids. Describe what you expect to see.
