What is the density of sulphuric acid if 35.4 mL of the acid weighs 65.14 g?

To find the density of sulfuric acid, we can use the formula for density, which is defined as mass divided by volume. In this case, we have the mass of the sulfuric acid and its volume, so we can easily calculate the density.

Calculating Density

The formula for density (D) is:

D = M / V

Where:

• D = density
• M = mass
• V = volume

Given Values

From your question, we have:

• Mass (M) = 65.14 g
• Volume (V) = 35.4 mL

Performing the Calculation

Now, we can substitute the values into the density formula:

D = 65.14 g / 35.4 mL

When we perform the division:

D = 1.838 g/mL

Understanding the Result

The density of sulfuric acid in this case is approximately 1.84 g/mL. This value indicates that sulfuric acid is denser than water, which has a density of about 1 g/mL. This property is significant in various applications, such as in chemical reactions and industrial processes, where the density can affect how substances mix and react.

Real-World Implications

Knowing the density of sulfuric acid is crucial for tasks like dilution, where precise measurements are necessary to ensure safety and effectiveness. For instance, when mixing sulfuric acid with water, it's important to add acid to water, not the other way around, to prevent exothermic reactions that can cause splattering or boiling.

In summary, the density of sulfuric acid, based on the provided measurements, is approximately 1.84 g/mL, which highlights its significant density compared to many other liquids, including water.
