The density of ethanol is 0.789 g/cm3 at 20 degrees celsius. What is the mass of 150cm3 of this alcohol?
To find the mass of ethanol, we can use the formula:
Mass = Density x Volume
Given:
Density of ethanol = 0.789 g/cm³
Volume of ethanol = 150 cm³
Substituting these values into the formula, we get:
Mass = 0.789 g/cm³ x 150 cm³
Now, we can calculate the mass:
Mass = 118.35 g
Therefore, the mass of 150 cm³ of ethanol is 118.35 grams.
