A bag of Hershey's Kisses contains the following information:
Serving size: 9 pieces = 41 g
Calories per serving: 230
Total fat per serving: 13 g
(b) The density of a Hershey's Kiss is 1.4 g/mL. What is the volume of a single Hershey's Kiss?
Guida verificata passo dopo passo1
Determine the mass of a single Hershey's Kiss by dividing the total mass of a serving by the number of pieces per serving. Use the formula: \( \text{Mass per Kiss} = \frac{\text{Total mass per serving}}{\text{Number of pieces per serving}} \).
Use the given density of a Hershey's Kiss to find the volume. Recall the formula for density: \( \text{Density} = \frac{\text{Mass}}{\text{Volume}} \).
Rearrange the density formula to solve for volume: \( \text{Volume} = \frac{\text{Mass}}{\text{Density}} \).
Substitute the mass of a single Hershey's Kiss and the density into the rearranged formula to calculate the volume.
Express the volume in milliliters (mL), as the density is given in grams per milliliter (g/mL).

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Density
Density is defined as the mass of an object divided by its 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 an object occupies relative to its mass. In this context, knowing the density of a Hershey's Kiss allows us to calculate its volume using the formula: Volume = Mass / Density.

Density Concepts
Volume Calculation
Volume is a measure of the three-dimensional space an object occupies. For irregularly shaped objects, volume can be calculated using the formula derived from density. In this case, to find the volume of a single Hershey's Kiss, we will use the total mass of one piece and the known density, applying the formula: Volume = Mass / Density, where mass is the weight of one Kiss.

Unit Conversion
Unit conversion is the process of converting a quantity expressed in one set of units to another. In this problem, it is important to ensure that the mass of a Hershey's Kiss is in grams to match the density's units (g/mL). Understanding how to convert between different units is essential for accurate calculations, especially when dealing with measurements in chemistry.
