The Volume of Ethanol With a Mass of 15.5 Grams

How can we calculate the volume of ethanol with a mass of 15.5 grams?

We know that the density of ethanol is 0.789 g/cm^3 at 20 degrees C. Given the mass provided, how can we find the volume of ethanol?

Calculation:

Given the formula:

density = mass / volume

We can rearrange it to:

volume = mass / density

Plugging in the values:

volume = 15.5 g / 0.789 g/cm^3

Volume of ethanol with a mass of 15.5 grams is approximately 20 cm^3.

When dealing with the density of an object, we need to consider the mass per unit volume. In this case, the density of ethanol at 20 degrees C is 0.789 g/cm^3. It means that for every cubic centimeter of ethanol, it weighs 0.789 grams. To find the volume of ethanol with a mass of 15.5 grams, we use the formula density = mass / volume.

Calculating the Volume:

To find the volume, we rearrange the formula to solve for volume: volume = mass / density. By substituting the given values, which are the mass of 15.5 grams and the density of 0.789 g/cm^3, we can calculate the volume. The volume of ethanol with a mass of 15.5 grams is approximately 20 cm^3.

It is essential to understand the relationship between mass, volume, and density in calculations involving physical properties of materials. By applying the formula correctly and manipulating it to solve for the unknown variable, we can determine specific characteristics of substances like ethanol.
