The problem asks to calculate the volume of dimethyl sulfoxide (DMSO) that a student should pour out, given the following:

- Mass of dimethyl sulfoxide (DMSO) needed: 30.0 g
- Density of DMSO: 1.10 g/cm³

To calculate the volume, we can use the formula:

\[
\text{Volume} = \frac{\text{Mass}}{\text{Density}}
\]

Substituting the given values:

\[
\text{Volume} = \frac{30.0 \, \text{g}}{1.10 \, \text{g/cm}^3} = 27.27 \, \text{cm}^3
\]

Since 1 cm³ is equivalent to 1 mL, the volume in milliliters is also 27.27 mL. Rounding this to three significant digits gives:

\[
\boxed{27.3 \, \text{mL}}
\]

Here are 5 related questions for practice:
1. If the student needs 50.0 g of DMSO, what volume should they pour out?
2. How would the volume change if the density of DMSO were 1.20 g/cm³?
3. How is the concept of density used in everyday applications?
4. Can you describe how to convert between cm³ and liters?
5. If the density of another liquid was 0.85 g/cm³, what mass would occupy 100 mL?

**Tip:** Remember, for any calculations involving density, ensure that the units of mass and volume are consistent before performing the division.

A chemistry student needs 30.0 g of dimethyl sulfoxide for an experiment. By consulting the CRC Handbook of Chemistry and Physics, the student discovers that the density of dimethyl sulfoxide is 1.10 g/cm³. Calculate the volume of dimethyl sulfoxide the student should pour out. Round your answer to 3 significant digits.

Learn how to calculate the volume of dimethyl sulfoxide using mass and density. In this problem, a student needs 30.0 g of dimethyl sulfoxide, and its density is 1.10 g/cm³. We use the formula Volume = Mass / Density to find the volume. Suitable for high school chemistry students.
