Use Table $2.9$ to solve the following problems: a. A graduated cylinder contains $18.0 \mathrm{~mL}$ of water. What is the new water level after $35.6 \mathrm{~g}$ of silver metal with a density of $10.5 \mathrm{~g} / \mathrm{mL}$ is submerged in the water? b. A thermometer containing $8.3 \mathrm{~g}$ of mercury has broken. If mercury has a density of $13.6 \mathrm{~g} / \mathrm{mL}$, what volume spilled?c. A fish tank holds 35 gal of water. Using the density of $1.00 \mathrm{~g} / \mathrm{mL}$ for water, determine the number of pounds of water in the fish tank.

Key Concepts

Density

Density is a physical property defined as mass per unit volume. It is used to relate the mass of a substance to the volume it occupies and is typically expressed in units such as grams per milliliter (g/mL) or kilograms per cubic meter (kg/m³). Understanding density is crucial for converting between mass and volume in various scientific calculations.

Volume Displacement Principle

The volume displacement principle states that when an object is fully submerged in a fluid, it displaces a volume of that fluid equal to its own volume. This concept is used to determine the new fluid level in containers when an object is added, making it fundamental in applications involving fluid mechanics.

Unit Conversion

Unit conversion involves changing measurements from one set of units to another using conversion factors. This is essential when dealing with different measurement systems such as mass units (grams, pounds), volume units (mL, liters, gallons), and length units. Mastery of unit conversions ensures accuracy in scientific calculations and practical applications.

Dimensional Analysis

Dimensional analysis is a method used in problem-solving to check the consistency of units and systematically convert one set of units to another. It involves multiplying by conversion factors to cancel out unwanted units, ensuring that the final calculation has the correct units, which is especially useful in chemical and physical calculations.

Mass-Volume Relationship

The mass-volume relationship describes how mass and volume are interconnected through density. By knowing any two of these quantities—mass, volume, and density—one can calculate the third. This relationship is fundamental in various fields such as chemistry, physics, and engineering for tasks like determining the displacement of fluids or calculating the weight of a liquid.
