How many grams of ethanol are present in 13.2 ml of liquid with a density of 0.78 g/ml?

To determine how many grams of ethanol are in 13.2 ml, we can use the formula:

Mass (g) = Volume (ml) × Density (g/ml)

Here’s how to calculate it:

• The volume of ethanol is 13.2 ml.
• The density of ethanol is 0.78 g/ml.

Now substitute the values into the formula:

Mass = 13.2 ml × 0.78 g/ml = 10.296 g

So, there are approximately 10.30 grams of ethanol in 13.2 ml. This calculation shows how the density of a liquid can help convert volume to mass safely and easily.
