b. An experiment requires 50.0 g of a substance called n-hexane, whose density at 25 °C is 0.6606 g/mL. What volume of n-hexane should be used?

검증된 단계별 안내

Identify the given values: mass of n-hexane = 50.0 g and density of n-hexane = 0.6606 g/mL.

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

Rearrange the formula to solve for volume: \( \text{Volume} = \frac{\text{Mass}}{\text{Density}} \).

Substitute the given values into the rearranged formula: \( \text{Volume} = \frac{50.0 \text{ g}}{0.6606 \text{ g/mL}} \).

Calculate the volume to find out how much n-hexane should be used.

주요 개념

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

Density

Density is defined as the mass of a substance per unit volume, typically expressed in grams per milliliter (g/mL) or kilograms per cubic meter (kg/m³). It is a crucial property that helps determine how much space a given mass of a substance will occupy. In this case, the density of n-hexane is provided, allowing us to calculate its volume based on the mass given.

Volume Calculation

Volume can be calculated using the formula: Volume = Mass / Density. This relationship shows how mass and density are interrelated, enabling the determination of how much space a substance occupies. By rearranging this formula, we can find the volume of n-hexane needed for the experiment based on its mass and density.

Units of Measurement

Understanding units of measurement is essential in chemistry, as it ensures accurate calculations and conversions. In this problem, mass is given in grams (g) and density in grams per milliliter (g/mL), which allows for direct volume calculation in milliliters (mL). Being proficient in unit conversions is vital for solving problems involving different physical quantities.
