What is the density of glass in g/cm3 if a sample weighing 27.43 g has a volume of 12.40 cm3?

검증된 단계별 안내

Identify the given mass of the glass sample, which is 27.43 grams.

Identify the given volume of the glass sample, which is 12.40 cm^3.

Recall the formula for density, which is \( \text{Density} = \frac{\text{Mass}}{\text{Volume}} \).

Substitute the given values into the density formula: \( \text{Density} = \frac{27.43 \, \text{g}}{12.40 \, \text{cm}^3} \).

Calculate the density using the substituted values to find the density in grams per cubic centimeter (g/cm^3).

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Density

Density is defined as the mass of an object divided by its volume, typically expressed in grams per cubic centimeter (g/cm³) for solids and liquids. It is a physical property that helps identify substances and can be calculated using the formula: Density = Mass/Volume. Understanding density is crucial for solving problems related to the mass and volume of materials.

Mass and Volume

Mass is a measure of the amount of matter in an object, usually measured in grams (g), while volume is the amount of space that an object occupies, measured in cubic centimeters (cm³) or liters (L). In the context of the question, knowing both the mass of the glass sample and its volume is essential to calculate its density accurately.

Units of Measurement

In chemistry, it is important to use consistent units of measurement to ensure accurate calculations. The question uses grams for mass and cubic centimeters for volume, which are compatible units for calculating density. Understanding how to convert between different units, if necessary, is also vital for solving problems in chemistry.
