The density of ethanol is 0.789g/cm3 at 20 degreesC. What volume of ethanol has a mass of 15.5 grams?
Mass = volume x density
You know density and mass, substitute and solve for volume
To determine the volume of ethanol that has a mass of 15.5 grams, you can use the formula:
Volume = Mass / Density
In this case, the mass of the ethanol is given as 15.5 grams, and the density of ethanol is specified as 0.789 g/cm³ at 20 degrees Celsius.
Plugging in the values into the formula:
Volume = 15.5 g / 0.789 g/cm³
Now, to obtain the volume in cubic centimeters (cm³), divide the mass (in grams) by the density (in g/cm³) to cancel out the grams units:
Volume = 15.5 g / 0.789 g/cm³ = 19.63 cm³
Therefore, the volume of ethanol with a mass of 15.5 grams is approximately 19.63 cm³.
