Ethanol has a density of 0.789 grams per centimeter ubed. How many cubic centimeters of ethanol must be poured into a graduatedcylinder to equal 30.3 grams?
mass = volume x density.
volume = mass/density
volume = 30.3/0.789 = ??
16.2
To determine the volume of ethanol required, we need to use the equation:
Volume = Mass / Density
Given:
Density of ethanol = 0.789 g/cm³
Mass = 30.3 g
Substituting the values into the equation:
Volume = 30.3 g / 0.789 g/cm³
Calculating:
Volume ≈ 38.42 cm³
Therefore, approximately 38.42 cubic centimeters of ethanol must be poured into the 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
In this case, the density of ethanol is given as 0.789 grams per cubic centimeter, and the mass we want to achieve is 30.3 grams. Let's rearrange the formula to solve for the volume:
Volume = Mass / Density
Substituting the given values:
Volume = 30.3 grams / 0.789 grams per cubic centimeter
Now use a calculator to divide 30.3 by 0.789 to find the volume:
Volume ≈ 38.414 cubic centimeters
So, approximately 38.414 cubic centimeters of ethanol must be poured into the graduated cylinder to equal 30.3 grams.
