Introduction

Density is a fundamental concept in chemistry that plays a crucial role in understanding the properties of various substances. It is defined as the mass per unit volume of a substance, and it is an essential parameter in determining the physical and chemical properties of a substance. The formula for density is given by $p=\frac{M}{V}$, where $p$ is density, $M$ is mass, and $V$ is volume. In this article, we will explore the concept of density, its formula, and how to calculate it using the given values of mass and volume.

Understanding the Formula for Density

The formula for density is a simple yet powerful tool that allows us to calculate the density of a substance given its mass and volume. The formula is based on the principle that density is equal to the mass of a substance divided by its volume. This means that if we know the mass and volume of a substance, we can calculate its density using the formula $p=\frac{M}{V}$.

Calculating Density Using the Given Values

To calculate the density of a substance, we need to know its mass and volume. In this case, we are given a substance with a mass of 27.82 grams and a volume of 3.6 ml. To calculate the density, we can plug these values into the formula $p=\frac{M}{V}$.

# Import necessary modules
import math
mass = 27.82  # mass in grams
volume = 3.6  # volume in ml

density = mass / (volume * 1000)  # convert ml to liters

print("The density of the substance is:", density, "g/cm^3")

Converting Units

When calculating density, it is essential to ensure that the units of mass and volume are consistent. In this case, we are given the mass in grams and the volume in milliliters (ml). To calculate the density, we need to convert the volume from milliliters to liters, as the formula for density requires the volume to be in liters.

Rounding Errors

When calculating density, it is essential to consider rounding errors. Rounding errors can occur when we round the values of mass and volume to a certain number of significant figures. In this case, we are given the mass and volume with three significant figures. To minimize rounding errors, we can use the formula $p=\frac{M}{V}$ and calculate the density using the given values.

Significant Figures

When calculating density, it is essential to consider significant figures. Significant figures are the number of digits in a measurement that are known to be reliable. In this case, we are given the mass and volume with three significant figures. To ensure that the result is accurate, we can use the formula $p=\frac{M}{V}$ and calculate the density using the given values.

Conclusion

In conclusion, the formula for density is a simple yet powerful tool that allows us to calculate the density of a substance given its mass and volume. By understanding the formula and how to calculate it using the given values, we can determine the physical and chemical properties of a substance. In this article, we have explored the concept of density, its formula, and how to calculate it using the given values of mass and volume.
