Ethanol (grain alcohol) has a density of 0.789 grams per centimeter cubed, How many cubic centimeters of ethanol must be poured into a graduated cylinder to equal 30.3 grams?
To find the volume of ethanol required to equal 30.3 grams, we can use the density formula:
Density = Mass / Volume
Given that the density of ethanol is 0.789 grams per cubic centimeter, and the mass we want to achieve is 30.3 grams, we can rearrange the equation to solve for volume:
Volume = Mass / Density
Substituting the given values:
Volume = 30.3 grams / 0.789 grams per cubic centimeter
Calculating the volume:
Volume = 38.465 cubic centimeters
Therefore, you would need to pour approximately 38.465 cubic centimeters of ethanol into the graduated cylinder to equal 30.3 grams.
